Church of Saint Ilya in Orša, Eastern Orthodox church in Orsha, Belarus

Church of Saint Ilya is an Orthodox place of worship built in Russian Revival style with red brick construction, multiple domes, and detailed window frames. The building follows traditional Orthodox architectural design and stands as a recognizable landmark in Orsha.

Founded around 1460 by Polish king Casimir Jagiellon in memory of his wife Elizabeth's rescue from drowning on Saint Elijah's feast day, the church had already existed and burned in 1447. It burned repeatedly, including in 1824 and on 3 May 1894, when a child's prank destroyed it and the nearby Saint Sophia church. The present stone building was erected in 1895–1896 and consecrated in 1898.

The church stands in Zadvinye, the left-bank suburb historically called Ilyinskaya Sloboda, and served as a cemetery church when Orsha belonged to the Polish-Lithuanian Commonwealth. A ferry crossing of the Dnieper operated nearby, where left-bank district residents held fairs. From 1961 to 1990 it was the only functioning church in the city, and until 14 November 1995 it held the status of Orsha cathedral.

Visitors can enter outside of regular prayer services, though active worship times are important to respect. It helps to check in advance when services take place to better plan your visit.

The church stands on the left bank of the Dnieper in the Zaddnieprovye district, opposite the old hillfort, at Ilyinskaya Street 1. Nearby was a Dnieper crossing where left-bank residents of the district held fairs. From 1961 to 1990 it was the only church in Orsha, and until 14 November 1995 it held the status of cathedral.
