Sir Humphrey Appleby: I put it to you, Minister, that you are looking a Trojan horse in the mouth!
James Hacker: If we look closely at this gift horse, we'll find it full of Trojans?
Bernard Woolley: If you had looked a Trojan horse in the mouth, Minister, you'd have found Greeks inside. Well the point is, it was the Greeks who gave the Trojan horse to the Trojans, so technically, it wasn't a Trojan horse at all, it was a Greek horse.
Beware of gifts bearing Greeks.
In the simplest version, the Greeks simply hide inside a object which they know the Trojans will be unable to resist picking up and taking inside their defenses. If the Trojans aren't complete idiots, subterfuge will be used to get them to accept the object — anything from disguising it as a Trojan vehicle up to a full-blown Gambit Roulette. Common variations include hiding a well-trained animal inside the Trojan Horse, or a computer program. In Speculative Fiction the Horse itself might be a robot or shape shifter.
Whatever the details, the net result is the same. The Greeks get some of their agents inside the Trojans' walls, without the Trojans knowing they are there, which leaves the Greeks free to commit sabotage, assassinate the Trojan leader, or simply open the gate and let the rest of their friends in.
This contrasts with such tropes as Trojan Prisoner, I Surrender, Suckers, and the nailfile-in-the-cake trick, because in those cases the Trojans do know the Greeks are there, and are trying, however sloppily, to guard them. Thus, the Greeks don't usually have the degree of free rein the Trojan Horse gambit gives them.
It also contrasts with using similar tricks to smuggle inanimate objects inside the Trojan lines, typically poisons and explosives, since such objects can't make decisions. A Greek soldier, or even a well trained monkey, is adaptable. They can change plans in mid-stream, taking advantage of unexpected opportunities. Poison can't do that. Thus, a Trojan Horse allows many more narrative possibilities than do inanimate objects.

- White Heat has Cody Jarrett and his gang using an empty tanker truck to smuggle themselves into a chemical plant so they can rob its payroll office. Cody lampshades this by mentioning that he got the idea from a story his mother had told him:
Cody: Way back there was a whole army tryin' to knock over a place called Troy and gettin' nowhere fast. Couldn't even put a dent in the walls. And, uh, one mornin', one mornin' the people of Troy wake up, look over the walls and the attackin' army's disappeared. Men, boats, the works. Taken the powder. But they left one thing after them: a great big wooden horse. And, according to Ma...

- Parodied twice over in the Discworld series:

- Star Wars Legends:
- In Wraith Squadron, the titular squadron uses a captured pocket carrier to ambush a Star Destroyer.
- In Heir to the Empire, Thrawn uses one in a clever application of a cloaking device. The (realistic) weakness of cloaking devices in his stories is that they are double blind and therefore difficult to use properly in conventional combat. He comes up with a clever solution: cloak the cargo bay and fill it with TIE fighters. Scanners would show the bay is empty and once they got into range the fighters could launch inside the enemy shipyard. It is only partially successful thanks to the timely intervention of Wedge and Rogue Squadron as well and Han, Luke and Lando.
- In David Gemmell's Troy Series, the Trojan Horse is actually an elite unit of Trojan cavalry led by prince Hector. In the final book, the unit is wiped out in an ambush and the Greeks dress up in the distinct armor worn by the cavalrymen. They then fool the Trojan defenders into thinking that survivors of the Trojan Horse are retreating toward the city and a gate is opened to let them in. The gate defenders are slaughtered and before reinforcements can close the gate, the rest of the Greek army storms in and sacks the city.

Mike then breaks out a drill, which is enough to cause the electromagnetically sensitive Chuck to panic and hide upstairs, but not to the point of shooing Mike away. Chuck had just exploited his own illness to get at Jimmy, and Jimmy is now acting in kind.

- Investigating the casino robbery in "Suckers", the CSI crew soon discover that a thief had been hiding inside a replica suit of antique Japanese armor, which was placed in the secure room with other valuables. Subverted in that the casino's owner had actually arranged the theft himself, so only acted like he'd been fooled by the Trojan Horse tactic.

- The Axonite given to Earth by the Axons in "The Claws of Axos".
- Also deliberately invoked in "Underworld" and "The Armageddon Factor".
- Not to mention the several occasions on which the TARDIS (with occupants) has been hauled into the stronghold of the opposition, either as a valuable piece of technology or merely a curiosity.
- "The End of the World": As part of the villain's plan, the other guests on Platform One are given gifts (the soiree includes the exchanging of "gifts of peace") with spider-robots hidden inside, which the guests than carry into their suites past all the security systems. The robots can then go out and wreak havoc on the station's systems.
- Part of The Caper in the Farscape episode "Liars, Guns and Money" involves hiding Rygel in a cargo container, then depositing the container in the bank they are intending to rob.
- The final episode of Leverage features a trojan murder investigation: the team fakes their own deaths, then attaches themselves to the investigation leading to said deaths (which allows them free access to a room they were unable to break into on their own). Sterling references this explicitly, calling himself a trojan horse after realizing he'd been duped into unlocking that room and letting them in.
- An earlier episode featured a variation. When Hardison is captured, the villainous executive assumes that there is no possible way that the incriminating files he had just finished deleting could now get out. While Hardison and his hard drive had no way out that didn't apply to the executive and his cell phone, which Hardison had just finished downloading the files to before he was captured. Parker manages to lift the phone after Hardison convinces him to go outside. There was also the fact that while the incriminating files were the original objective, they weren't the most valuable thing on those servers, that would be the food patents that the company owned. Nate is able to use those to leverage the executive into turning himself in.
- The Mission: Impossible team uses tricks like this to get people or equipment into or out of the area they are operating in, regularly.
- The NCIS episode "Trojan Horse". A guy gets into the evidence locker to tamper with evidence by hiding in the stuffing of a seat of a taxi made to look like a crime scene.
- On NUMB3RS, a group of criminals plan to kill a prisoner who is about to turn state's evidence. Their plot involves an overly complicated scheme that first involves killing power to sections of LA to cause the prison to run their generators out of fuel. As more fuel is required, the criminals hide inside the fuel truck to plan their entry into the prison. However Fridge Logic kicks in when you realize that the tanker was empty. Apparently the prison guards fail to check the inside of the truck or even tap the side to see it is empty.
- Sharpe and the Chosen Men did this at least twice. Once with the youngest of their number groaning on a stretcher while the French-speaker shouted about cholera, once with Harper covered in blood from a pulled tooth and pretending to be mortally wounded until the time came to attack.

- One story on Urban Legends featured a midget thief who robbed bus passengers by hiding in a large duffel bag, which an accomplice set out with other riders' luggage for the driver to stash in the cargo bins.
- The Wire has a few examples.
- Lieutenant Charles Marimow. When the Major Crimes Unit is causing problems for Rawls, Rawls has Marimow take over command and disrupt the unit from within. Marimow forces the unit to focus on "street rips," which is the exact thing the unit was created to get away from, rendering the MCU useless. Rawls even calls him "Marimow, my Trojan Horse," making clear that he uses Marimow to break up any unit causing problems for him.
- In "All Due Respect", Omar Little gets into a Barksdale stash house disguised as an old man in a wheelchair, claiming to be related to the home's owner. He even has the guards carry him up the stairs before he pulls out his gun.
- In season 3, the Major Crimes Unit is trying to track the burner phones used by Avon Barksdale's gang, but it's impossible to get a tap on them because they replace them every two weeks. McNulty and Greggs find out that Bernard, the runner assigned to make the pickup runs, is buying them in packs of two at each store to avoid suspicion, which is much to his girlfriend Squeak's annoyance. The unit has Kima's informant Bubbles (who doesn't know Bernard, but used to know Squeak) approach Squeak claiming that he can hook them up with a black market cellphone salesman who can cheaply sell them burner phones in bulk for a low discount. Said "black market cellphone salesman" is actually an undercover Lester Freamon, who through his "Cool Lester Smooth" talking, is able to convince Bernard and Squeak to bulk-buy pre-tapped phones.
- The Yes, Minister episode "Bed of Nails" uses the term for a task that would mean political suicide for the clueless minister James Hacker, who has been duped into accepting the position. This leads to this page's opening quote. Next, he becomes confused with Ancient Grome (since he did not attend Oxbridge).
Bernard Woolley: Hence the tag "Timeo Danaos et dona ferentes", which you'll recall, is usually and somewhat inaccurately translated as "Beware of Greeks bearing gifts". Or doubtless you would have recalled had you not attended the LSE.
James Hacker: Greek tags are all very well, but can we stick to the point?
Bernard Woolley: No, the point is, Minister, just as the Trojan horse was Greek, what you call a Greek tag is, in fact, Latin. It's obvious, really: The Greeks would never suggest bewaring of themselves, if one can use such a participle, and it's clearly Latin not because "Timeo" ends in "o", as the Greek first person also ends in "o". No, there is a Greek word "Timao" meaning "I honour", but the "os" ending is a nominative singular termination of a second declension in Greek and an accusative plural in Latin, though actually Danaos is not only the Greek for Greek, it's also the Latin for Greek.
- It doesn't actually happen in The Iliad. It's mentioned in The Odyssey, but the actual event isn't depicted in either poem, but rather in the other, lost epics of the Trojan Cycle. It is described in flashback in The Aeneid by Vergil, though, and that is why the line "Timeo Danaos et dona ferentes" is Latin.
The original is far more flattering to both sides than the simple version usually taught in elementary schools. In the original, the Greeks simply cannot take Troy, try as they might, because Poseidon has placed over the city a protective veil. So they construct a great wooden image of a horse, the sacred animal of Poseidon, then except for the few men concealed within the image, withdraw from the city, beyond any range from which they could attack, with a message placed before the image that reads, "For the honour of Troy and the glory of Poseidon." The Trojans are then forced either to reject the gift, which will likely offend Poseidon who will then withdraw his protection from the city, or bring it inside, which will require them to partly dismantle the gate and thus rend the veil. Either way, the veil is down and the Greeks have at least a fighting chance to take the city.
- Semi-inverted, but with the same intent in the Battle of Luthien during BattleTech's Clan invasion. A group of Industrial 'Mechs were armed with long range weapons and armor to disguise them as actual BattleMechs, but were actually ActionBombs, set to go off when the Clan forces closed in to get inside the minimum range of the decoys.
Shin Yodama: A new variant on the old Trojan horse strategy. Instead of letting them take the horse into their castle, we had to lure them into the herd, but it worked nonetheless.

- In Exalted, one of the Deathlords, the Lover Clad in the Raiment of Tears, constructed a noble warstrider for the sole purpose of allowing the government of Lookshy to capture it and take it to their capital. Apparently, it contains a booby trap that, when triggered, will turn most of the country into a shadowland, allowing her legions to swoop in and conquer the whole place with hardly a shot fired. She hasn't triggered it yet, though, because she's Brilliant, but Lazy.
- Magic: The Gathering: Akroan Horse. You gift it to an opponent when it's played and, in turn, it gives soldiers to their opponents. Loads of fun in multiplayer games.
- A ploy like this is responsible for the continued existence of video games as a medium. After The Great Video Game Crash of 1983, stores were reluctant to sell consoles, or even anything that looked like a console because everybody was sick of them, and people wouldn't buy what they were sick of. Then along came Nintendo, marketing the Robotic Operating Buddy as a conventional toy and allegedly providing the NES as a bonus instead of the other way around. While the R.O.B unit itself was nothing special, the ruse allowed the NES to enter everyone's homes and made people realize that the medium was, in fact, not so dead after all. This is listed as #5 on Game Spy's Top 25 Smartest Moments in Interactive Entertainment.

- In Starcraft II: Wings of Liberty, the heroes storm the Dominion weapon research facility and steal a Super Prototype of a Humongous Mecha scheduled to be shipped to the Dominion capital world to lead a parade.

- The title characters of Ed, Edd n Eddy use one in the form of a giant, fake pull-string doll to sneak back into Ed's house after being kicked out by Sarah and Jimmy. Not surprisingly, it's not convincing enough to fool Sarah and instead of going back into the house, the Eds end up at the top of a lamppost.
Jimmy: A talking dolly!Eddy: (from inside) Say something, stupid!Ed: My head is snoring! Make it stop!Jimmy: AAAHH! Sarah! Boogeyman!

- Another episode shows them reenacting the Trojan War. At its culmination, Buford has Irving get into a trojan platypus. Phineas doesn't fall for it, but it proves to be a decoy as the war takes a turn into Out-of-Genre Experience territory when Buford and Ferb appear with a Trojan T-Rex armed with modern day weapons that stomps on the platypus.

- Speedy Gonzalez: Sylvester is trying to keep Speedy out of the cheese factory. At one point Sylvester braces himself to catch Speedy, only to have a baseball thrown at him instead. An irritated Sylvester then flings the baseball into the cheese factory. Speedy is inside the hollowed-out baseball.
- Star Wars: The Clone Wars: In "Pursuit of Peace", sabotage droids are delivered to Coruscant disguised as cleaning droids.
- Star Wars Rebels: In "Homecoming", a rebel strike team gets onboard an Imperial carrier via a stolen TIE bomber and a staged attack by two A-Wings.
- Happens in The Super Mario Bros Super Show! episode "Trojan Koopa". Instead of a horse, Mario, Luigi and Toad build a giant wooden statue of King Koopa himself, banking on his ego to take the bait. Adding to the trick is that earlier they grabbed two of his Troopas and sent them out to sea with a dummy to make it look like they were giving up.
- In Time Squad, the Squad go back to the time of the original Trojan Horse, only to find that the Greeks filled the horse with candy. After a little coaching, they send in a wooden giraffe... full of little chocolate soldiers. Finally, the Greeks send over a giant wooden soldier full of horses... which run wild and wreck Troy.
- The Underdog sideshow Go Go Gophers has a short titled "Trojan Totem" where the Coyotes receive a totem pole from the Gopher Indians, and at night, the Gophers inside sneak out and sabotage the fort.
- In "Castle Caper" on Wallykazam!, Wally sends his dragon Norville inside a cake as a trojan horse to the castle that Bobgoblin has taken over. He, however, makes the mistake of posing as a delivery guy in a Paper-Thin Disguise and telling him that he has the cake that ordered, allowing Bobgoblin to get into an Argument of Contradictions with him about whether or not he ordered a cake until finally Norville makes noise and gives himself away.
- Done in Xiaolin Showdown, but with a twist; Jack Spicer sends the heroes a giant statue of him holding a fruit basket, but the Dragons, citing this trope, break apart the statue. However, Jack wasn't in the statue- he was hiding in the fruit basket!
- In computing, a "Trojan horse" or more simply "trojan" is a virus that disguises itself as an innocuous program and sneaks past anti-virus programs to infect computers. They don't self-replicate, but are harder to spot and can royally mess up infected computers.
- Real viruses also qualify, as they trick the cells they invade into taking them inside, using features on their surfaces that resemble nutrients the cell requires.
- A hilarious case of Unfortunate Names: Trojan Condoms. Either they're named for the city, which had its defenses fall, or it refers to the horse, which got the city to open their defenses so they could be ravaged. Upon that last thought, perhaps Fridge Brilliance rears its head...note
- During the The Eighty Years' War, the Spanish-occupied city of Breda was taken by the Dutch and English forces through a Trojan Horse style tactic; despite the siege, a barge loaded of winter fuel, in this case peat, was still allowed to enter and leave the city, and none of the Spanish garrison checked the barge. So, hidden under the piles of peat, a group of soldiers led by Charles de Heraugiere had themselves smuggled into the city and took the Spanish forces inside by surprise. The attackers killed forty defenders without any loss, and by dawn Sunday March 4 the men of Heraugiere had already taken control of most the city.
