Placencia Peninsula is a small town located in the Stann Creek District of Belize. In the late 20th century it became a significant tourism destination, and is now referred to as Placencia Village or simply Placencia.
The eastern side of the Peninsula is a long expanse of white sand beach and heavy mangrove in some areas; the western side is bounded by a long narrow north-south trending bay of the Caribbean Sea. A significant settlement on the peninsula is the Garifuna village of Seine Bight. Placencia is served by Placencia Airport. The village is home to 458 permanent residents according to the 2000 census.
