The Frat Pack is a colloquial fan term for a group of actor[=/=]writer[=/=]director[=/=]all-round-movie-guys who specialise in comedy.

The name "Frat Pack" originates from one of their early defining works, ''Old School''; not as a phrase dropped in-show but as a reference to their [[ManChild post-teen]] [[RefugeInAudacity juvenile]] brand of comedy, while alluding to names like "RatPack" or "Creator/BratPack" given to other known groups of actors.

The Frat Pack comprises Creator/BenStiller, Creator/JackBlack, Creator/WillFerrell, Luke Wilson, Creator/VinceVaughn, Owen Wilson and Creator/SteveCarell.
