Saint Catherine Church in Feodosia, Orthodox church building in Feodosia, Ukraine

Saint Catherine Church in Feodosia is a Russian Orthodox church built in the pseudo-Russian style, its plan based on a Greek cross. The walls stand on a high socle and are divided at the corners by columns; a portico with a small bell tower forms the west entrance. Five small blue domes covered with stars rise above a band of carved kokoshniks.

The church was founded on 21 April 1892, the birthday of Empress Catherine II, and built with donations from Feodosia residents. Mathematician Vasily Lapshin gave a large sum, merchants supplied materials, and workers laboured free on weekends. Closed by Soviet authorities in 1937 and used as a warehouse, it was returned to worshippers in 1941 under German occupation and has remained active since.

The church keeps a Sunday school for Feodosia's Cossack community, whose "Stanitsa Feodosiyskaya" held its first lesson on the grounds on 19 June 2016. A chapel to Blessed Xenia of Petersburg opened here on 6 February 2018, the first in the Feodosia-Kerch diocese dedicated to her.

The building sits at Fedko Street 95 and is easily accessible on foot from central areas. Additional facilities including a Sunday school and educational centers operate alongside the main house of worship for community use.

The Chapel of Blessed Xenia of Petersburg was opened on the church grounds on 6 February 2018, blessed by Metropolitan Platon, after repeated requests from Orthodox residents of Feodosia. The Feodosia-Kerch diocese had no church dedicated to this saint before.
