- Hero #1: Tall, usually dark, and definitely handsome. Almost always has a past. While highly unlikely to actually mistreat the heroine, he's not above scaring her into submission (however, as he's often dealing with Heroine #1, it's unlikely to work).
- Hero #2: This is the consummate gentleman, who invariably comes up with the perfect response to any situation. Their usual role is to provide the heroine with an escape from any difficulties, whereas Hero #1 is frequently the cause of those difficulties.
- Heroine #1: A lively young woman. She naturally gets herself into many a social scrape, from which the hero must rescue her, and either bounces back or feels humiliated deep down inside that he saw her in such a state.
- Heroine #2: Overlooked and ignored, she may seem quiet. However, once the hero talks to her, or needs help, Heroine #2 comes into her own and reveals Hidden Depths.
Tropes present in most Heyers include:
- Asshole Victim: Always present in her whodunnits.
- Author Appeal: Expect at least one kiss to be described as "crushing."
- Costume Porn: Clothing will be described in loving detail. As many of her heroes are Sharp Dressed Men, the men's clothing will very likely be described in even more detail than the women's.
- Deadpan Snarker: Hero #1 almost certainly; frequently Hero #2 as well. Less common but far from unknown among the heroines; it may come up as part of Heroine #2's Hidden Depths. Given Heyer's milieu, the character is usually a Gentleman Snarker as well.
- Happily Ever After
- Historical-Domain Character: Her Regency and historical novels are peppered with cameo appearances by real people.

- Corrupt the Cutie: Lethbridge's intention for Horatia. Eventually leads to I Have You Now, My Pretty, foiled by a Tap on the Head.
- Duel to the Death: Two, in fact, although neither ends in death.
- Gambit Pileup: Lady Massey is out to get Rule back; Lord Lethbridge is out to compromise Horatia in order to humiliate her husband; Drelincourt wants to destroy the marriage so he won't be displaced in the succession to the Earldom; Viscount Windwood wants to protect his sister; Horatia wants to save her marriage - and Rule wants exactly the same thing.

- The Gambling Addict: Several members of the Winwood family have "the fatal weakness."
- Gem-Encrusted: Horatia buys a pair of shoes with emerald-studded heels.
- The Highwayman: Played with. If a highwayman appears, either someone hired him for an ulterior purpose, or he's a major character in disguise.

- Love Dodecahedron: Horatia is in love with her husband, and her husband is in love with her, but neither know it.

Horry very sensibly goes to Rule who is marrying for the bloodline not love, and asks if she won't do instead? He decides she would.
- Zany Scheme: Any plan Horry and her brother come up with.
- Attractive Bent-Gender
- Bedsheet Ladder: How Pen escapes her room, which leads to the Meet Cute.

- All Girls Want Bad Boys: Subverted.
- Betty and Veronica: Freddy is Betty and Jack is Veronica for Kitty.
- Camp Straight: Freddy, who is not a Casanova, cares deeply about fashion, and is very fastidious about rules of proper conduct. He is considered so safe for women that men don't mind him being around their wives and Kitty uses him as her fake fiance, knowing that he won't take advantage of this and want to marry her himself. But he is certainly straight, and becomes protective of her to the point of violence, which shocks everybody he knows, and eventually falls in love with her.
- Chaste Hero: Freddy. Often mistaken by readers as latent or closeted homosexual (see above) , but as a matter of fact there is no sign of his being attracted to anybody until Kitty comes along, of course. He is, because of this trope, considered so harmless, that other men don't mind him spending time with their wives.
- Converting for Love: It's mentioned in passing that Olivia will probably have to become a Catholic to marry Camille.

- Genius Ditz: Freddy.
- Grand Romantic Gesture: Parodied: Camille makes extravagant proclamations of what he would do to save Olivia, but is surprised when practical Freddy suggests simply eloping with her. Also played subtly straight with Freddy submitting to a day of sightseeing with Kitty.

- Secret Relationship: Freddy and Kitty pretend to have one of these.

- "Blackmail" Is Such an Ugly Word: The Asshole Victim tried this, simply to become The Chessmaster of the county.
- Driven to Suicide: The Smug Snake's late brother claimed this is what the Smug Snake had done to him in a letter... Actually, it was murder made to look like suicide, which the Asshole Victim was blackmailing the Smug Snake about, hence why he was killed.
- This Is a Work of Fiction: As Heyer herself states at the very beginning of the book:There are some who may believe that this book is about them. They are, in fact, mistaken.
- All Girls Want Bad Boys: Although Mary mocks Vidal as being no more than bratty and not nearly as bad as he thinks he is.

- Parental Marriage Veto: Mary fully expects one of these from Vidal's parents, so she runs away before they get there; averted because they both thoroughly approve of her.
- Poirot Speak: Léonie.

- Lovable Coward: Ferdy, whom Sherry can't even stay angry with when he finds out Ferdy hid his wife from him for weeks because Ferdy is so shamelessly trying to placate him.
- Love Dodecahedron: Both Sherry and George court Isabella Milborne (along with many other men). Sherry marries Hero, who is in love with him. Hero and George find comfort in each other because they think (wrongly) that their loves are unrequited. This makes Isabella think that George is in love with Hero, and fall into a scrape with Sir Montagu Revesby. Meanwhile, Hero is courted by Mr Tarleton, which makes Sherry fall into another jealous rage.
- Love Epiphany: When Hero runs away, Sherry has this. In fact, the whole thing was staged so he could have this.
- Marry for Love: Isabella eventually cracks and admits that this is what she wants.
- Masquerade Ball: Hero gets into trouble at one of these as a result of Sherry ditching her.

- Reformed Rakes: Part of Sherry's Character Development.
- Relationship Upgrade: Sherry elopes with Hero in the first few chapters.

- Aww, Look! They Really Do Love Each Other: Charles and Sophy at the very end.
- Beta Couple: Cecilia and Charlbury, among others.
- Cleaning Up Romantic Loose Ends
- The Chessmaster: Sophy, of course.
- Genre Savvy: Sophy's management of the Augustus/Cecilia/Charlbury triangle relies heavily on her knowledge of how Cecilia perceives the tropes involved.
- Greedy Jew: Goldhanger, the moneylender, is very likely meant as one.

- Love at First Sight: Parodied with Cecilia and Augustus.
- Love Dodecahedron: The Grand Sophy has a wonderfully convoluted one: Charles is engaged to Eugenia, but falls in love with Sophy, who is in turn admired by Lord Bromford.

Augustus drops his love of Cecilia in favour of being temporarily infatuated with Sophy. Eugenia falls in love with Lord Bromford, and cuts her engagement to Charles, who then can propose to Sophy.

The Great Roxhythe
An Infamous Army
Lady of Quality
My Lord John
No Wind of Blame
- Rube Goldberg Hates Your Guts: The murder method is this in spades!
- Abusive Dad/Asshole Victim: Penhallow himself.
- Downer Ending: Unusual for a Heyer novel, but it's a doozy. Penhallow's death doesn't make things better; in fact, it makes things even worse. The family are drawn together even tighter, even though few of them wish to be so, and the eldest is Driven to Suicide because he thinks he'll be implicated by the Literal And Figurative Bastard, although on the last page it's revealed that the bastard in question did nothing of the sort. The police never catch the killer at the end, making the whole thing one big Shoot The Shaggy Dog Story. Some Heyer fans suspect that she was writing this book to make up for all the cheeriness in all of her other novels!
- Open Mystery: You know full well who killed Penhallow... and you don't blame her.
- Police Are Useless: The policeman in charge of the case actually thinks Penhallow was a pretty generous patriarch, and the rest of the family were just being whiny spongers.
- The Unfavourite: Technically, every one of Penhallow's children - legitimate or otherwise - qualify, but his youngest son definitely qualifies.
Pistols For Two
- Accidental Marriage: In "Hazard", the hero is so drunk when he wins the card game that he and the heroine are halfway to Gretna Green when he wakes up the next morning.
- Arranged Marriage: The hero of "Hazard" is about to go through with one of these; luckily for him, he has a Runaway Fiancé.
- Lost Him in a Card Game: "Hazard".
- Platonic Life Partners: Annabella and Tom from "Full Moon", who are very fond of each other and plan to elope only because Annabella is so horrified at the idea of marrying an old man.
- Repetitive Name: Carlington Carlington in "Hazard". Though that's probably a typo/omitted comma.
- Right in Front of Me: Annabella and Tom complain bitterly to a friendly stranger about the "horrid old friend" of Annabella's father whom she's expected to marry. Neither of them have ever met him, leading to predictable results.
Powder and Patch
- Be Careful What You Wish For: Cleone and Sir Maurice want Philip to learn to dress well and get some social graces. He does, but he is hurt that they forced him into it, so he can't resist acting like an affected fop when he returns.
- Duel to the Death: Philip fights three duels over the course of the book, though they are not to the death.
- Gay Paree: Eighteenth-century version.
- Giftedly Bad: In-universe, Philip's French friends insist he is this as a poet (though the one example of his poetry that we see is not bad at all).

- I Want My Beloved to Be Fashionable: Cleone feels this way toward Philip (and Sir Maurice agrees with her).
- Makeover Montage: Philip gets one (in text).
- Poirot Speak: From numerous French characters.

- She Cleans Up Nicely: Subverted as here it is the man who is condemned for being provincial and in need of acquiring some town polish. Used to comedic effect, as he cleans up very nicely, which leads to the Be Careful What You Wish For.
- Took a Level in Badass: Philip becomes an expert fencer along with his other accomplishments.
The Quiet Gentleman
- Cain and Abel: Theodore wants to make it look like this trope, arranging his traps for St Erth to make it look as though Martin was trying to murder his brother.

- Historical In-Joke
- I Am Not Pretty: Drusilla thinks this.
- Love Dodecahedron: Drusilla is interested in St Erth, who along with Theodore, Martin and Viscount Alderston are all interested in Marianne, who in turn is only interested in the Viscount.
- The Mole
- The Unfavourite: St Erth is this to his stepmother.
- Agent Peacock: Rule. He is one of the dandy set, closely befriended with dandy-in-chief Beau Brummel, and Judith is convinced that all dandies are horrid sissies, only to be shocked to find them actually kind of classy, very well dressed and in the case of Rule surprisingly badass. Rule is a skilled boxer, who can knock another man out cold when it becomes necessary.
- Belligerent Sexual Tension: Judith really does not get on with Worth for about half the book.
- Jerk with a Heart of Gold: Worth, who is busy being an arse to Judith's face while protecting her from fortune-hunters and her brother from murderers behind her back.

- Big, Friendly Dog: Bouncer, except when he's guarding Elinor. Then he morphs into Angry Guard Dog.

- The Dandy: Francis. And how. He could also be seen to be something of an Agent Peacock, as it transpires he is actually a cold-blooded killer.
- I Never Said It Was Poison: How Carlyon deduces that Francis killed de Castres; he knew details about the murder that were not in any of the newspaper accounts.
- MacGuffin: The missing document.
- One Dialogue, Two Conversations: A hilarious one between Elinor and Carlyon at the start of the book. Carlyon thinks Elinor has answered his advertisement for a woman to marry his cousin, while she thinks he's discussing a governess position.
- Promoted To Parent: The main reason, according to Elinor, for Carlyon's overbearing nature, was that he had to take charge of his younger siblings (and Eustace) from a relatively early age.
- Secret Path: The hidden entrance to Highnoons.
- Secret Relationship: The cover story for why Eustace suddenly has a wife.
- Chivalrous Pervert: Charles Stuart is an unashamed womanizer but he will not take advantage of an honest young woman who is helping him at the risk of her life.
- Historical In-Joke:
- King Incognito: Charles II. He is in fact a little too comfortable with incognito to suit some of his stiffer supporters.
- Nice to the Waiter: Charles is tired, hurt and scared but he makes an effort to be courteous and friendly to the common folk helping him.
Simon the Coldheart
The Spanish Bride
- Annoying Younger Sibling: Hester's brother, despite being older, fulfils this trope; Hildebrand at one point pretends to be this to Amanda and Gareth.

- Shrinking Violet: Hester.
- Spirited Young Lady: Amanda.
- The Tale: Amanda spins about a dozen of these throughout the novel.
- True Companions: Gareth, Hester, Amanda and Hildebrand. Neil would probably have been adopted one way or another had the book been longer.
- Arranged Marriage: Played with. Sylvester wants one, but his mother is reluctant to arrange anything for him. When he presses she confesses that she had at one point thought to maybe match him with her deceased friend's daughter. She doesn't actually arrange the thing still, Sylvester merely decides that he will see Phoebe for himself, without knowing that he had, unwittingly, insulted her when he had been introduced to her during the Season. Hilarity ensues.

- Like Brother and Sister: Phoebe and Tom.
- Mouthy Kid: Edmund.

The Talisman Ring
These Old Shades
- Aloof Big Brother: Avon.
- Annoying Younger Sibling: Rupert and Fanny.
- Best Served Cold: The enmity between Avon and St. Vire goes back twenty years.

- I Have No Son: Arthur Billington-Smith tried to do this and that was why he was killed.
- Mama Bear: The murderess was Billington-Smith's first wife, making sure her son wasn't disinherited. The unfinished clue is the word "There", the last thing he wrote. In spite of most people not paying too much attention to it, TheInspector realises it's the first letters of Theresa, the Major's first wife.
The Unknown Ajax
- Crusty Caretaker: Spurstow (a handy way of making people reluctant to visit him).
- The Dandy: Claud.
- Girlfriend in Canada: Upon finding out that Lord Darracott intends for him to marry Anthea, Hugo invents a fiancée back in Yorkshire. (Anthea has already said that she doesn't want to marry him, but apparently he feels he must be more tactful.)
- Inspector Javert: Lieutenant Ottershaw with his near-fanatical pursuit of smugglers.
- Kissing Cousins
- Mysterious Past: Hugo, eventually revealed.
- My Valet-Fu is Stronger Than Yours: Crimplesham and Polyphant (Vincent and Claud's valets, respectively) spend a great deal of time trying to one-up each other.
- Obfuscating Stupidity
- Ooh, Me Accent's Slipping: Aunt Aurelia is the only character to notice that Hugo's Oop North accent goes away, rather than appears, when he's not paying attention.

- Brother-Sister Team: Aubrey and Venetia have elements of this.
- Byronic Hero: Damerel is this.
- Cool Big Sis: Venetia.
- Dark and Troubled Past: Damerel.
- Double Standard: Played with; Damerel arguably suffered more for running off with a married woman than she did.
- Emo Teen: Oswald, who desperately wishes he was a Byronic Hero."He is brooding over nameless crimes, I daresay, and only think how disheartening to have his dark thoughts mistaken for a fit of the sulks!"
- Faking the Dead: Venetia's mother ran off with a lover and was divorced by her father; he told the children that she had died suddenly.
- Forceful Kiss: Oswald tries this on Venetia.
- The Ghost: Conway is often talked about, and various of his offstage actions are important to the plot, but he never appears.
- Hello, Nurse!: Venetia, and also her mother.
- It's Not You, It's My Enemies: Damerel sends Venetia away due to the irreparable damage that would be done to her reputation if they married.
- I Want My Beloved to Be Happy: Damarel pretends that his flirtation with Venetia had only been a pleasant game, and makes her leave, because he thinks she deserves better than him, and because of his reputation (see above).

- Nobody Thinks It Will Work: Everyone, with the exception of Aubrey and Venetia – and including Damerel – thinks Damerel and Venetia will be miserable together.

- Pair the Spares: It's hinted that Edward Yardley and Clara Denny will probably marry after being rejected by Venetia and Conway, respectively.
- Reformed Rakes: Played with more than used straight. Damerel won't seduce Venetia, but it's up to interpretation how much his way of life will change. He might just be joking about having his wife preside over an orgy...
Why Shoot A Butler?
- Amateur Sleuth: Frank Amberley—the person who solves the mystery—is a barrister, although it's noted in the story that he has some experience rounding up major criminals, having helped the police at least once.
- Crazy-Prepared: When the Big Bad tries to get away via a motorboat, Frank just happens to have a motorboat of his own ready. Justified in that he'd done some research during the previous day, and figured that would happen.
- Police Are Useless: Averted. the police are just at sea because there are no clues to go on, and Amberley has quite a few of them... not that he tells the police most of them.
- Slap-Slap-Kiss: It doesn't help that Frank is something of a troll throughout the whole book, and not just to the girl.
- Smug Snake: Frank Amberley is this, making him something of a Designated Hero.
