The McPoyles in It’s Always Sunny: Who Plays Whom?
Meet the McPoyle family in It’s Always Sunny in Philadelphia, including Liam, Ryan and Margaret, with actors and appearances.
The McPoyles in It’s Always Sunny: Who Plays Whom?
The McPoyles are a recurring fictional family in It's Always Sunny in Philadelphia, known for uncomfortable behavior and clashes with the main characters. Liam and Ryan are the most recognizable brothers, while Margaret and other relatives add to the group's odd dynamics. This is a guide to the on-screen family, not a biography of one performer.
Liam, Ryan and Margaret
Liam McPoyle is played by Jimmi Simpson. His brother Ryan is played by Nate Mooney, and Margaret McPoyle is portrayed by Thesy Surface. Their appearances across the series turn the family into a recurring source of escalating absurdity. The brothers may be visually easy to confuse in a short clip, so the character and actor pairings help identify them.
The McPoyles are deliberately written as exaggerated, unsettling figures. Their behavior is a feature of dark sitcom humor and should not be presented as ordinary family advice or real-life information about the performers.
Why the family keeps returning
The McPoyles give the show's core group recurring antagonists whose grudges can be picked up in later episodes. Unlike a one-off customer or neighbor, they arrive with a shared history that makes their appearance itself a joke. Their awkward social behavior and elaborate feuds allow the sitcom to extend a gag across seasons.
As a result, a general search for 'the McPoyles' usually seeks cast identities and memorable episodes rather than the filmography of Jimmi Simpson alone. A single family guide is the best home for Liam, Ryan and Margaret instead of fragmenting each name into near-identical pages.
How to identify the cast
Jimmi Simpson has many non-McPoyle roles, including Westworld, so his career should be treated separately. The same is true for the rest of the cast. A clip showing the McPoyle family is not sufficient evidence that a performer shares any character trait off screen. For episode-specific questions, check the original episode's cast credits because not every relative appears every time.
