The Gulf or Bay of Honduras is a large inlet of the Caribbean Sea, indenting the coasts of Belize, Guatemala, and Honduras. From north to south, it runs for approximately 200 km from Dangriga, Belize, to La Ceiba, Honduras.

The inner Gulf of Honduras is lined by the Belize Barrier Reef which forms the southern part of the 900 km long Mesoamerican Barrier Reef System, the second-largest coral reef system in the world. The Belize Barrier Reef includes a number of small islands, called cays, and collectively known as the Pelican Cays.

The Gulf of Honduras is marked by complex dynamics of coastal and open waters, and ocean currents, which have produced a very diverse and unique ecosystem with a wide variety of coastal marine waters, including coastline estuaries, barrier beaches, lagoons, intertidal salt marshes, mangrove forests, seagrass beds, keys and barrier reefs.

The gulf receives the runoff from the watersheds of 12 rivers with an estimated discharge of 1232 m³ s⁻¹. These rivers include the Moho, Sarstún, Río Dulce, Motagua, and Ulúa. Increased volumes of sediments drained in the Gulf of Honduras pose a threat to its marine ecosystem.

Many American anglers visit the Gulf of Honduras to catch the marlin that abound there. Tourists are often taken on boat trips to the Pelican Cays, notably Caye Caulker and Ambergris Caye.

In 1961 Hurricane Hattie swept across the Gulf of Honduras, destroying buildings in Belize.
