York Castle Museum is a museum located in York, North Yorkshire, England, on the site of York Castle, originally built by William the Conqueror in 1068. The museum itself was founded by Dr John Kirk in 1938, and is housed in prison buildings which were built on the site of the castle in the 18th century, the Debtors Prison (built in 1701-05 using stone from the ruins of the castle) and the Female Prison (built 1780-1785).

The museum's displays include recreated period rooms such as a Victorian parlour and a Jacobean dining room, displays of every day life in Dr. Kirk's Gallery and the Hearth Gallery, and craft workshops in the cells of the old Debtors Prison. There is also a recreation of a Victorian street (Kirkgate, named after Dr. Kirk). What was once an Edwardian street (Half Moon Court) is now an exhibit on the 1960s. The museum also has a Barn Gallery, a Children's Gallery and military and costume displays. The former Condemned Cell, possibly once occupied by Dick Turpin, can also be visited.
