Republican Erzya Museum, Art museum in Saransk, Russia.

The Republican Erzya Museum is an art museum in Saransk, the capital of the Republic of Mordovia in Russia, dedicated mainly to sculpture and painting. The collection brings together the works of sculptor Stepan Erzia and paintings by Russian masters from different periods.

A gallery was first decided on in 1941, but the war prevented it from opening. The Mordovian Republican gallery named after Fedot Sychkov opened on 10 January 1960 on Sovetskaya Street. It was reorganised into a museum of visual arts in 1978, and the name of Stepan Erzia was added in 1995.

The museum is named after the sculptor Stepan Dmitrievich Erzia, who carved many of his figures from Argentine woods like quebracho and algarrobo. These dark, dense materials give the sculptures a raw, almost living quality that visitors notice as soon as they enter the main hall.

The main building is at 61 Kommunisticheskaya Street, and the exhibition hall at 29 Sovetskaya Street stands beside the Mordovian Drama Theatre, joined to it by a single-storey link. The two wings of the main building are connected on the second floor. The museum is closed on Mondays.

Stepan Erzia spent nearly three decades in Argentina and created most of his work there before returning to the Soviet Union in 1951. He brought around 180 sculptures with him on the return journey, unwilling to leave his work behind.
