TSS Great Western was a passenger vessel built for the Great Western Railway in 1933.
She was built in 1933 to replace an earlier ship of the same name, which had operated from Fishguard, a coastal town in Pembrokeshire, Wales, to Rosslare Harbour in Wexford, Ireland, since 1902. She was launched on 21 November, 1933 by Lady Cadman, wife of Sir John Cadman, a director of the Great Western Railway, and had an experimental type of coal firing with mechanical stokers and a forced draught system, intended to be more economical than oil.
From April to August in 1944, she performed as a troop ship, but returned to service and continued until 1966 when the service was abandoned
