Union Island stamps highlight one of the most distinctive dependencies within the Grenadines of St. Vincent. Issued from the late 1960s onward, these stamps allowed Union Island to appear by name, giving the small southern Grenadine a recognizable postal identity within the British Commonwealth system.

Designs typically feature Queen Elizabeth II paired with vivid pictorial scenes celebrating the island’s maritime culture and natural environment. Sailing vessels, coral reefs, tropical fish, flowers, and coastal landscapes dominate many issues, reflecting Union Island’s reputation as a center for yachting and seafaring in the southern Caribbean.

This category includes definitive and commemorative issues inscribed “Union Island – St. Vincent,” with many sets appealing strongly to topical collectors of ships, marine life, and island scenery. Compact, colorful, and visually engaging, Union Island offers a rewarding collecting area for enthusiasts of Caribbean philately and Grenadine island issues.
