The Tuxedo Princess (ex-TSS Caledonian Princess) and Tuxedo Royale (ex-TSS Dover) were two former car ferries used as permanently moored floating nightclubs in the United Kingdom from the 1980s to the 2000s. Both ships saw use on the River Tyne at different times, while the Princess also saw use on the River Clyde in Glasgow, and the Royale on the River Tees in Middlesbrough.
