Kubinka Tank Museum, Military museum in Kubinka, Russia

The Kubinka Tank Museum is a military museum in Kubinka, Moscow Oblast, Russia, displaying over 350 armored vehicles and fighting machines from fourteen countries. Six large pavilions organize the collection by origin and type, while an outdoor area presents additional exhibits in the open air.

Founded in 1938 as the Museum of Combat Vehicles, the museum grew out of the classified armour testing and proving ground at Kubinka, where new Soviet designs and captured German, Japanese and Western tanks were evaluated. It opened to visitors on 10 September 1978, Tankman's Day. Since 2014 it has been part of the Patriot military theme park.

The museum serves as a center for technical research, preservation of military heritage, and international cooperation through regular exchanges with institutions in Germany, France, and Britain.

The museum lies in Kubinka, Odintsovsky District, and is reached by suburban train from Moscow's Belorussky station. It is still part of a military base: weapons and alcohol are banned and security staff check entrants with metal detectors. Foreign visitors should carry both their passport and a copy. Filming vehicles is covered by the entrance fee.

Among the exhibits stands the Panzer VIII Maus, the heaviest fighting vehicle ever built, weighing more than 180 tons (163 metric tons). Beside it sits the Karl-Gerät self-propelled siege mortar, a weapon with a 600 millimeter (24 inch) caliber used during the Second World War.
