A series of {{Platform Game}}s by Creator/DataEast. The series began with the 1991 UsefulNotes/ArcadeGame ''Caveman Ninja'', known as ''Joe & Mac: Tatakae Genshijin'' ("Fighting Cavemen") in Japan. Set in {{Prehistoria}}, the object of the game is to [[DamselInDistress rescue the titular duo's harem of]] [[NubileSavage cave girls]] from a band of rival cavemen and their dinosaur pet bosses. ''Joe & Mac: Caveman Ninja'' saw quite a few home ports (with or without the subtitle), namely the UsefulNotes/SuperNES, UsefulNotes/SegaGenesis, UsefulNotes/NintendoEntertainmentSystem, UsefulNotes/GameBoy, Amiga, DOS, and Zeebo.

It was followed by two SNES sequels: ''Congo's Caper'' (1992) and ''Joe & Mac 2: Lost in the Tropics'' (1994). There was also an arcade spin-off in 1994 titled ''Joe & Mac Returns'', an EliminationPlatformer similar to Data East's ''VideoGame/TumblePop''.

On November 6th 2009, French developer GolgothStudio announced that they were working on a [[http://golgothstudio.com/devblog/category/joe-mac/ new installment in the series in DLC format]]. Lack of updates since then places the new Joe & Mac squarely in DevelopmentHell for the time being.

! This game provides examples of:
* AbhorrentAdmirer: [[spoiler:If you go down the middle and lower paths after the final boss, the ending will show you being chased by either an overweight middle-aged cavewoman or a male neanderthal in a drag. Though Joe and Mac have the same scared reaction when they're being chased by groupies.]]
* AndYourRewardIsInteriorDecorating: In ''Lost in the Tropics''.
* BambooTechnology: Mook cavemen riding foot-powered wooden helicopters. They throw bombs at you, for some odd reason.
** In the village in Joe and Mac 2, a primitive telescope and pulley are present.
** The final boss of Joe and Mac Returns is a wooden GiantMecha. When you destroy it, the rider continues fighting you in one of the wood helicopters.
* BoundAndGagged: The cavegirls, all tied up in various forms during boss fights. This [[{{Bowdlerise}} was removed from the SNES version]] for obvious reasons.
** The redheads and brunettes are tied to poles.
** The raven-haired ones are under UnwillingSuspension.
** The blondes simply have their hands tied behind their backs.
* ChargedAttack: Only in the arcade version. If you take too long to fire, it will tire your caveman out, and you'll take damage.
* ChivalrousPervert: In ''Joe & Mac Returns'', when the two heroes aren't out rescuing cavegirls, Joe and Mac try to peep at them while they're bathing, blow their bikinis tops off, or just outright steal their bikinis.
* ColorCodedMultiplayer
** Joe (Player 1) - green
** Mac (Player 2) - blue
* DoppelgangerAttack: Only in the arcade version, it's the duo's only "ninja" attack.
** The FinalBoss in the first game ''sort of'' does this, but the doppelganger transforms into one of the other cavemen to attack.
* ForTheEvulz: The first level in ''Joe & Mac 2'' would have ended without a boss fight, if it weren't for some random neanderthal whacking a sleeping stegosaurus on the head ForTheLULZ.
* GiantSpaceFleaFromNowhere: The first game has two final bosses, depending on which version you play. Most versions feature [[spoiler: some sort of caveman-dinosaur hybrid that attacks by leaping at you in rapid somersaults, and spitting up larvae-like creatures. The NES game's manual identifies him as 'The Fabled Sagileocorn', whatever that means.]] The SNES version instead has [[spoiler: a BigRedDevil, complete with pitchfork and demonic cackle, who turns into a more challenging blue form when you beat him.]] Both of them count; even moreso since they are both fought inside of a t-rex, for some reason.
* HeadSwap: Joe and Mac themselves, plus the redheaded and brunette cavegirls.
* InventingTheWheel: One of many weapons in the game.
* KillItWithFire: One of the stronger weapons in the game.
* MamaBear: The first boss, a tyrannosaurus rex, awakens once you hurt its offspring.
* ManEatingPlant: The second boss which bears an [[LawyerFriendlyCameo incredible resemblance]] to [[Theatre/LittleShopOfHorrors Audrey the second]]. It can [[TentacleRope grab]] and eat you, which is an [[CaptainObvious instant kill.]]
** In the original arcade version and NES port, the plant will actually spit out your bones. This was removed from the Genesis port, Game Boy port, and SNES arrangement.
* NinjaPirateZombieRobot: In ''Congo's Caper'', an almost literal example of this trope are the four caveman bosses you must fight after the intro stages. 2 of them are actually a ninja and pirate, respectively. One is technically a vampire, but is nonetheless undead like a zombie, and the last guy isn't a robot, but he is a MadScientist who builds a dinosaur robot out of ''[[BambooTechnology wood and stone]]''.
* [[ThePiratesWhoDontDoAnything The Ninjas Who Don't Do Anything]]: Despite the title Joe and Mac don't have any ninja powers except for the DoppelgangerAttack.
* PaletteSwap: The cavegirls and some of the enemies.
* PowerupMount: Two levels have your cavemen ride on either pterodactyls or brontosauruses.
* SequelNumberSnarl: ''Joe & Mac 2'' is known as ''Tatakae Genshijin 3'' in Japan and ''Joe & Mac 3'' in Europe. The Japanese title makes sense, since ''Congo's Caper'' was ''Tatakae Genshijin 2'' over there, but the change from ''Joe & Mac 2'' to ''Joe & Mac 3'' is a bit more puzzling (unless they were counting ''Joe & Mac Returns'' as "Joe & Mac 2", which came out almost at the same time).
* ShoutOut: Upon defeating one of the bosses, your player will [[VideoGame/BadDudes pump a fist in the air]].
** Also, there's Cola as a collectible food item, which was common in Data East games.
* SmoochOfVictory: After every boss fight, the rescued cavegirl will kiss your character on the cheek, restoring his health. If two players are playing, only the one who dealt more damage to the boss gets it (much to the other's chagrin).
* WingedSoulFliesOffAtDeath: If either Joe or Mac lose all their energy, they transform into winged souls and fly off in the series.
* WizardNeedsFoodBadly: Its possible for your caveman to fall over dead from starvation in some versions, such as the arcade version, where your life gradually decreases (most versions, such as the SNES version, don't have this feature). Or more hilariously, fall over dead from starvation soon after surviving an attack with one HP left.
* WombLevel: Results in a giant realistic-looking beating heart as a backdrop.
* YouGottaHaveBlueHair: Well, Mac does. Joe's hair is green.
