Alexander Nikolaevich Evreinov (8 March 1877 – 20 August 1959) was a Russian bishop, who converted to Russian Greek Catholic Church from Russian Orthodoxy. Being a citizen with a noble origin in Saint Petersburg, Evreinov was a member of the Foreign Affairs department of the Russian nation before his conversion to the Catholic faith and ordination to the priesthood. Despite being consecrated as a bishop in 1936, Evreinov did not have any jurisdiction among Russian Catholics, either in the Soviet Union or in the Russian diaspora. Evreinov was a member of the Russian Apostolate.
