HMS Conway was a naval training school or "school ship", founded in 1859 and housed for most of her life aboard a 19th-century wooden ship of the line. The ship was originally stationed on the Mersey near Liverpool, then moved to the Menai Strait during World War II. While being towed back to Birkenhead for a refit in 1953, she ran aground and was wrecked, and later burned. The school moved to purpose-built premises on Anglesey where it continued for another twenty years.

A training ship is a ship used to train students as sailors. The term is mostly used to describe ships employed by navies to train future officers. Essentially there are two types: those used for training at sea and old hulks used to house classrooms. As with receiving ships or accommodation ships, which were often hulked warships in the 19th Century, when used to bear on their books the shore personnel of a naval station, that were generally replaced by shore facilities commissioned as stone frigates, most "Training Ships" of the British Sea Cadet Corps, by example, are shore facilities.
