TSS Duke of Lancaster

TSS Duke of Lancaster is a former railway steamer passenger ship that operated in Europe from 1956 to 1979, and is beached at Llannerch-y-Mor Wharf near Mostyn Docks, on the River Dee, in north Wales. She replaced an earlier 3,600-ton ship of the same name operated by the London Midland and Scottish Railway company between Heysham and Belfast.

As of 2021 she was owned by Anthony Rowley and The Duke of Lancaster Appreciation Society.
