The Brat Pack is a nickname given to a group of young actors who frequently appeared together in teen-oriented coming-of-age films in the 1980s. First mentioned in a 1985 New York magazine article, it is now usually described as the cast members of two specific films released in 1985 – The Breakfast Club and St. Elmo's Fire – although other actors are sometimes included. The "core" members are considered to be Emilio Estevez, Anthony Michael Hall, Rob Lowe, Andrew McCarthy, Demi Moore, Judd Nelson, Molly Ringwald, and Ally Sheedy.

The actors themselves were known to dislike the label. Many of their careers peaked in the middle of the 1980s but had interruptions afterwards for various reasons. However, the films they starred in together are frequently referenced in popular culture and are regarded as some of the most influential of their time.
