The Church of Christ the Savior, St. Catherine the Great Martyr, and St. Seraphim of Sarov, also known as the Russian Church, is a parish church of the Western European Diocese of the Russian Orthodox Church Abroad and is located in San Remo, Italy. Until January 2019, the parish belonged to the Western European Exarchate of Russian parishes under the jurisdiction of the Patriarchate of Constantinople.

The idea of building the church arose among the Orthodox residents of San Remo, mainly vacationers from Russia, with the support of a charitable and construction committee that included Vladimir Sabler, V. S. Sheremetyev, V. I. Galevich, T. Debero, A. M. Sukhanina, G. E. Tillo, and engineer Tornatore. The restoration of the church after the war and its continued existence became possible thanks to the efforts of the San Remo city administration, lawyer Fuzaro, A. N. Vlasov, wardens M. A. Stansfield, Efremova, and N. Sperarli-Burmazovich, as well as the rector, Archpriest Ioann Yankin.

On the church grounds, two monuments have been erected dedicated to King of Italy Victor Emmanuel III and his wife Elena of Montenegro, who was an Orthodox princess before her marriage. Elena's parents, King of Montenegro Nikola I Petrovich and Milena Vukotic, were buried in the church crypt in 1921 and 1923, respectively, but in 1989 their remains were transported back to their homeland at the request of their Montenegrin relatives.

During World War II, a bomb hit the church, piercing the roof but failing to explode, becoming lodged in the floor.
