This category includes postage stamps issued by Russia, encompassing both Imperial and modern issues, as well as stamps from the Union of Soviet Socialist Republics (USSR). Together, these stamps document one of the most extensive and visually diverse postal histories in the world.

Common themes range widely, including czars and imperial emblems, Orthodox churches, space exploration, industrial achievements, military commemorations, propaganda art, cultural figures, scientific milestones, and major architectural landmarks. Soviet-era stamps in particular are known for their bold graphic style, strong symbolism, and ambitious subject matter, while earlier Imperial issues and later Russian Federation stamps reflect changing political and artistic traditions.

Collected for their historical breadth, artistic variety, and global significance, Russia and USSR stamps offer collectors a deep and compelling journey through more than a century of political, cultural, and philatelic history.
