The Adelphi Cinema was a city centre film theatre on Middle Abbey Street, in Dublin, Ireland from 1939 to 1995.

This 2,304-seat Art Moderne style movie palace was designed by William R. Glen, (assisted by local Irish architect Robert Donnelly) for the Associated British Cinemas (ABC) circuit and opened on 12 January 1939 with Errol Flynn in The Adventures of Robin Hood.

While primarily a cinema, the Adelphi featured live acts as well, most notably the only appearance in Dublin by the Beatles on 7 November 1963.

Other performers who appeared at the Adelphi included the Beach Boys, Marlene Dietrich, Louis Armstrong, Diana Ross, and Roy Orbison.

The Adelphi Cinema was closed on 30 November 1995, screening High Society and Gigi, with no admission charged.
