Gulf of Santa Catalina

The eastern coast of the gulf belongs to the states of California, United States, and Baja California, Mexico.

The largest town on the shore of the gulf is San Diego.

The gulf covers an area of more than 100 sq mi (260 km2) and borders the east coast of Catalina and the beaches of Orange, Los Angeles, and San Diego counties.

The gulf is located in a seismically active area.
