San Telmo Museoa or San Telmo Museum is a museum of the Basque society located in Donostia-San Sebastián. The museum covers Basque history, arts and culture. Since 1932, it has been located in  a 16th century Dominican convent situated on Zuloaga plaza in the old town, at the foot of the Urgull hill.

Exhibitions are spread over the convent and the sympathetically integrated newer wing. The collection ranges from historical artefacts to bold fusions of contemporary art. San Telmo also stages some outstanding temporary exhibitions.
