The Diocese of Thailand () is a diocese of the Russian Orthodox Church which covers the territory Thailand, Cambodia, Laos, and Myanmar. It is part of the Patriarchal Exarchate in South-East Asia. History Eastern Orthodoxy in the region Since the mid-1990s, a large number of immigrants from the former Soviet Union came to Thailand. At that time, there was no Orthodox parishes in the entire territory of the Kingdom.
