The Grand Pavilion is an entertainment venue in Porthcawl, Bridgend County Borough, Wales, opened on 8 August, 1932 by Councillor Russell Mabley J.P., Chairman of P.U.D.C.

[1] It has an octagonal dome and extensive frontage, and was originally intended as a Palm Court for hosting tea dances, balls and civic functions.

Recently, names such as Rob Brydon, Eddie Izzard, Elkie Brooks, Cerys Matthews, Hayley Westenra, Katherine Jenkins, Suzi Quatro, Ralph McTell, Joe Pasquale, and Gerry & The Pacemakers have all appeared on the Pavilion's stage.

Originally named the "lesser hall" (and subsequently the "Jubilee Room") the basement of the Pavilion houses a refurbished performance space now named "The Stage Door", which plays host to regular comedy nights, folk and jazz nights, dance classes, theatre workshops, conferences and meetings.

The Cafe Bar hosts its own series of events, such as Jazz, Chill-out sessions, Literary speaking and an Art Forum.
