Pavilion Theatre (Irish: Amharclann an Phailliúin)[1][2] is a theatre, cinema and arts centre in Dún Laoghaire, Ireland.

The introduction of television led to a decline, and the last film shown for a long time was No Sex Please, We're British in 1974.

In the 1980s, Planxty recorded two programmes for RTÉ at the Pavilion,[5]: 274  and acts such as De Dannan, The Dubliners and the Dublin Ballet Company also performed at the venue.

[6] The Pavilion was closed in 1984 as a result of the enforcement of new fire regulations introduced with the Fire Acts of 1981 and 1982, and reopened in 2001 as a new 324-seat building.

[6][7][8] It is operated by Pavilion Theatre Management Company and owned by Dún Laoghaire–Rathdown County Council.
