The Tullie House Museum and Art Gallery is a museum in Carlisle, Cumbria, in England. Opened by the Carlisle Corporation in 1893, the original building is a converted Jacobean mansion, with extensions added when it was converted. At first the building contained the museum and also a library, an art school and a technical school.
The building, including the extensions, is a Grade I listed building, and the wall, gates and railings in front of the house are separately Grade I listed.
The two schools were moved in the 1950s and the library in 1986. The museum expanded into the city Guildhall in 1980 and with new space available from 1986 it underwent an extensive redevelopment over 1989-90 and again in 2000-01.
