Catalina is a community located on the eastern side of the Bonavista Peninsula, in the province of Newfoundland, Canada. Catalina adjoins the union town of Port Union, the town built for and home to the Fisherman's Union Company established by Sir William Coaker.
The name of the town is purported by E.S. Seary to derive from the French Havre Sainte-Katherine which was later changed to the Spanish name Cataluna.
In 2005 Catalina was amalgamated with Melrose and Port Union to form the town of Trinity Bay North.
