The Old Synagogue is a 19th century building at 19A Princes Street in central Auckland, New Zealand, that was formerly a synagogue. It is now called University House, and is part of the University of Auckland.
The old synagogue building was left vacant and deteriorated over the following years, until it was carefully restored in 1989 to serve as a branch of the National Bank. The University of Auckland has leased it since 2003, and it now houses the University's External Relations offices. The building has a Category I listing with the New Zealand Historic Places Trust.
