The Orthodox Church of Russia began its fundraising campaign in February, ekathimerini.com reported. By Tuesday it had raised about 500,000 euros ($625,000) through appeals to monasteries, churches and individuals.
Patriarch Kyrill urged Russians to help the growing number of homeless people in Greece.
"People see the problem in Greece as their own," a Russian church official said.
Sources told ekathimerini the money would go to soup kitchens run by the Greek Orthodox Church.
