St Sarkis (Armenian: Սուրբ Սարգիս եկեղեցի) is an Armenian Apostolic church and a Grade II* listed building in Iverna Gardens, Kensington, London. It was constructed in 1922–23 by Calouste Gulbenkian as a memorial to his parents, and the architect was Arthur Davis. It is the only church in England to have been built in the traditional Armenian style. Its design is inspired by the 13th century freestanding bell tower of Haghpat Monastery. It is the seat of the Diocese of the United Kingdom of the Armenian Apostolic Church.
