Three ships of the United States Navy have been named USS San Juan. The first retained her mercantile name when acquired by the Navy; the latter two were named for the capital of Puerto Rico.
The first USS San Juan (SP-1352) was acquired by the Navy from the San Juan Packing Company of Seattle and used as a minesweeper and patrol boat during World War I.
