Museum of Military History 1941-1945, Military history museum in Saransk, Russia.

The Memorial Museum of Military and Labour Feat of 1941–1945 stands on Victory Square in Saransk, in a building designed by architects A. Kostin and R. Kananin whose outline follows the borders of Mordovia. Its roof is stylised as a kokoshnik, the traditional women's headdress, and the facade is clad in granite slabs laid in black and orange stripes, the colours of the St George ribbon. Inside are four halls, including the Hall of Glory with a mosaic panel and the Hall of Commanders in the basement.

The museum opened on 6 May 1995, founded and first directed by Alexei Mikhailovich Mamaev. Its building, designed by architects A. Kostin and R. Kananin, was made part of the memorial complex of military glory on Victory Square. A branch, the A. I. Polezhaev Museum, opened in Saransk on 5 June 2001 in a restored 19th-century wooden house at 51 Saranskaya Street that once belonged to the merchant Myshkin.

The museum's name links military and labour feats: the Hall of Glory's mosaic panel honours both front-line soldiers and home-front workers. The Hall of Generals, in the basement, holds portraits of Russian commanders by I. V. Sidelnikov and a panoramic display of World War II small arms. A branch opened on 5 June 2001 in a restored wooden house at 51 Saranskaya Street, once owned by the merchant Myshkin, devoted to the poet Alexander Polezhayev, a Mordovia native.

The museum stands in the memorial complex on Victory Square; the four halls run from the ceremonial Hall of Glory down to the Hall of Commanders in the basement, and the open-air display of a T-54 tank, infantry fighting vehicles, guns, a howitzer and an M-1 anti-aircraft mount is beside the building.

The building's outline follows the borders of Mordovia, and its roof is styled after a kokoshnik, the traditional women's headdress. The granite cladding is laid in black and orange bands, the colours of the ribbon of Saint George.
