Martin [=McDonagh=] is an English-born Irish playwright and screenwriter best known for The Leenane Trilogy, ''TheLieutenantOfInishmore'' and the Oscar-nominated 2008 film ''InBruges''.

''The Leenane Trilogy'' consists of ''The Beauty Queen of Leenane'', ''A Skull in Connemara'', and ''The Lonesome West''. The Aran Islands Trilogy consists of ''The Cripple of Inishmaan'', ''TheLieutenantOfInishmore'', and the unproduced ''The Banshees of Inisheer''. Other plays include ''The Pillowman'' and ''A Behanding in Spokane''.

Before ''InBruges'', [=McDonagh=] also wrote and directed the short film ''Six Shooter'' (2004), for which he received an Oscar for Best Short Film. His third film, ''SevenPsychopaths'', was released in fall 2012.

[=McDonagh's=] works are generally [[BloodyHilarious violent]] [[BlackComedy black comedies]] that focus on [[DysfunctionalFamily dysfunctional families]], [[HitmanWithAHeart hired killers]], and/or a uniquely twisted form of SmallTownBoredom in County Galway (and surrounding islands) during UsefulNotes/TheTroubles. His brother, John Michael McDonagh, made his directorial debut with Film/TheGuard in 2011, and released ''Calvary'' in 2014. Like ''Six Shooter'' and Film/InBruges, they both star Brendan Gleeson.

!!Martin [=McDonagh's=] work contains examples of:

* BlackComedy
* BloodyHilarious
* BrickJoke: the apparent feud between the unseen owners of a cat and a goose; Helen being hired to dispose of said animals; the owners not seeming to care about the feud anymore (because it was a cover to their SecretRelationship).
* BuryYourDisabled: deconstructed in ''Cripple''
* ClusterFBomb
* CoveredInGunge: Bartley in ''Cripple'' gets at least three eggs cracked over his head every performance
* CreatorBreakdown: InUniverse in ''The Pillowman''
* DisabledCharacterDisabledActor: This trope is [[DiscussedTrope discussed]] InUniverse in ''Cripple''; the concept is PlayedWith in several ways, although the actor playing Billy is almost always able-bodied.
* TheDocumentary: "Man of Aran," a real 1934 ([[VeryLooselyBasedOnATrueStory docudrama]]) film.
* EverythingsEvenWorseWithSharks: A shark is hunted in "Man of Aran" and is apparently how Johnnypateenmike's father died. The widow turns the other cheek. To a shark!
* EvilMatriarch: Mag is the first type in ''Beauty Queen''.
* FakingTheDead: [=McDonagh=] LOVES this and its various subtropes. In the Aran Islands plays, it's a specific {{Homage}} to ''The Playboy of the Western World.''
* {{Gorn}}: Between the blood, gore, and kitty brain matter in ''[[TheLieutenantOfInishmore Lieutenant]]''; hot oil in ''Beauty Queen''; flying bone chips in ''A Skull in Connemara''; and [[ArsonMurderAndJaywalking raw eggs]] in ''Cripple'', it seems like [=McDonagh=] is off his game if he hasn't created a hideous mess for stage management to clean up every night.
* GossipyHens: rare male example in Johnnypateenmike, who is barters tidbits of information for goods from local merchants.
* [[HonoraryUncle Honorary Aunts]]: Kate and Eileen to Billy.
* IncurableCoughOfDeath: DoubleSubversion in ''Cripple.''
* KnowledgeBroker: Johnnypateenmike
* LeaningOnTheFourthWall: "Better to cast a normal fella who can act crippled, than a crippled fella who can't act at all."
* MaybeEverAfter: Billy and Slippy Helen in ''Cripple.'' FridgeBrilliance kicks in when you realize siblings Mairead and Davy in ''[[TheLieutenantOfInishmore Lieutenant]]'' share a last name with Billy Claven (established to have no living relatives) and many personality traits with Helen and her brother Bartley. [[DownerEnding That is, if Billy lives much longer after the play]].
* MommyIssues: Maureen in ''Beauty Queen''-- and ''how!''
* NeverLiveItDown: InUniverse: Auntie Katie, who talks to ''stones.''
* {{Oireland}} / NWordPrivileges: Early is his career, [=McDonagh=] received criticism for his depiction of the Irish, being born and raised in England himself.
* OnlySaneMan: He's an alcoholic mess, but Father Welsh in The Leenane Trilogy is pretty much the only one in the village to [[spoiler: never kill anyone]].
* ThePlace: All the plays in the Leenane and Aran Islands Trilogies feature a place-name or direction in their titles. ''A Behanding in Spokane'' and ''InBruges'' also qualify.
* PrecisionFStrike: From, [[CrowningMomentofFunny hilariously]], a little girl in ''The Pillowman.''
-->"I don't want to be ''like'' Jesus. ''I fucking '''am''' Jesus''!"
* ProsceniumReveal: [[spoiler: Cripple Billy]]'s death scene early in Act 2 is revealed to have been his Hollywood screen test.
* RepetitiveName: Katurian K Katurian in ''The Pillowman''. [[note]]In case you were wondering, the K stands for Katurian.[[/note]]
* RuleOfFunny: "Let's play England and Ireland!" [[CoveredInGunge *egg to the head*]]
* RunningGag: In ''Cripple'': "Ireland can't be so bad if [[[MadLibsCatchPhrase American, French, colored fellows]], [[ItMakesSenseInContext sharks]]] want to move here!"
* SeinfeldianConversation
* SorryBillyButYouJustDontHaveLegs
* StrangeSyntaxSpeaker: Most everyone, especially older characters. It's essentially what you would get if you crossed Hiberno-English with MametSpeak. The style was so distinctive it was parodied "How Are Things In Irish Drama?", the ForbiddenBroadway take on ''Beauty Queen''.
* TheXOfY: Several titles
