The stamps of Bulgaria reflect the nation’s rich history at the crossroads of Eastern Europe and the Balkans, from its emergence as a modern state in the late 19th century through monarchy, war, socialism, and contemporary independence. Early Bulgarian stamps are admired for their classic designs, including heraldic lions, royal portraits, and finely engraved definitives.

Throughout the 20th century, Bulgarian issues expanded into a wide range of commemorative and pictorial stamps highlighting history, folklore, archaeology, Orthodox Christianity, art, science, and international events. Bulgaria is also well known for its strong thematic output, appealing to collectors interested in culture, sports, space exploration, and nature. With a balance of classic material and visually striking modern issues, Bulgaria stamps offer depth and variety for European, Balkan, and worldwide collections.
