Santa Catalina Island, often called Catalina Island, or just Catalina, is a rocky island off the coast of the U.S. state of California. The island is 22 miles (35 km) long and 8 miles (13 km) across at its greatest width. The island is located about 22 miles (35 km) south-southwest of Los Angeles, California. The highest point on the island is 2,097 feet (639 m) Mt. Orizaba, at 33°22′29.7″N 118°25′11.6″W.
One of the Channel Islands of California archipelago, Catalina lies within Los Angeles County. Most of the island is administered by the Catalina Island Conservancy.
