Two ships of the Royal Navy have been named HMS Campania after the region of Campania in Italy:
The first Campania , purchased in 1914, was a passenger liner converted to a seaplanetender. She collided with Royal Oak and Glorious in 1918 and sank.
The second Campania (D48) was an escort carrier launched in 1943. She served in World War II and was broken up in 1955.
