Masjid Omar Ali Saifuddien, or the Omar Ali Saifuddien Mosque, named after the 28th Sultan of Brunei Darussalam, HM Sultan Haji Sir Muda Omar Ali Safuddien Sa'adul Khairi Waddien.

Built within the vicinity of Kampung Ayer (Water Village) in the early 1950's, one of the most oldest, if not the oldest, mosque in Brunei.

This is also one of the most photographed structures in Brunei, coming to Brunei without seeing or having a photo of the mosque can be considered as incomplete, as it is situated at the very heart of the capital of Brunei, Bandar Seri Begawan.
