The Chesme Church (; full name "Church of Saint John the Baptist at Chesme Palace", also called the "Church of the Nativity of St. John the Baptist", ), is a small Russian Orthodox church at 12 Lensoveta Street, in Saint Petersburg, Russia. It was built by the Russian court architect Yury Felten in 1780, at the direction of Catherine the Great, Empress of Russia. A memorial church, it was erected adjacent to the Chesme Palace (: damaged during the Siege of Leningrad and restored in 1946) between Saint Petersburg and Tsarskoye Selo to commemorate the anniversary of Russia's 1770 victory over Turkish forces in Chesme Bay () in the Aegean Sea during the Russo-Turkish War of 1768–1774.
