Holy Transfiguration Russian Orthodox Church, Russian Orthodox cathedral in Los Angeles, United States.

Holy Transfiguration Cathedral is a white Russian Orthodox church in Los Angeles with a square base and a tall central tower. Above the tower rise gold onion domes topped with crosses, the central one highest, with smaller domes on lower tiers and at the corners. A small blue and white sign sits on the front face above a dark archway.

In 1929 a group of Russian immigrants raised $50 to bring Archpriest Nikolai Kiklovich from Harbin; he served the first liturgy on 13 May 1930. Services moved between rented rooms until parishioners bought a building in 1937, consecrated on 17 October 1937. A 1948–1949 court case between ROCOR and the North American Metropolis ended in ROCOR's favour.

The feast of the Transfiguration is kept on August 6; in August 2004 Archbishop Kyrill consecrated the dome and cross on that day, and on October 12, 2004, the main dome and cross were raised onto the cathedral. After World War II a Russian school was set up at the church for the many Russians arriving in Los Angeles from Europe and the Far East.

The cathedral stands behind and to the right of a gas station canopy, with the entrance under the tower's dark archway; a small blue and white sign marks the front. The main dome and cross were raised on 12 October 2004, and the rector then spoke of a plan for twenty more domes and crosses.

On 12 October 2004 the main dome and cross were hoisted onto the tower; rector Alexander Lebedev then said the plan foresaw twenty more domes and crosses above the church. The theft of 22 December 2012 took sacred vessels and the altar cross, valued at over $50,000.
