Rafayel "Rafo" Israyelian (Armenian: Ռաֆայել Իսրայելյան; 17 September [O.S. 4 September] 1908 – 8 September 1973) was an Armenian architect.

Seen as a follower of Alexander Tamanian, Israyelian designed some of Soviet Armenia's most prominent structures, including the Sardarapat Memorial, the Yerevan Wine Factory and several churches, both in Armenia and abroad, most notably St. Sargis in Yerevan and St. Vartan in New York.
