Mercury Theatre, Historic theatre building in Waitematā, New Zealand.

The Mercury Theatre is a performance venue in Waitematā offering shows in a spacious hall. The structure displays architectural details from the early 1900s, with features typical of New Zealand construction practices of that era.

The theatre opened on November 28, 1910 and was among the first major performance venues in the Waitematā region. This early establishment makes it an important record of how the neighbourhood began developing its cultural life.

The name comes from the Mercury Theatre Company, which occupied the building from 1968 to 1991, not from a Roman god. The company staged at least 12 productions a year, from children's pantomimes to Shakespeare and Chekhov, and actors such as George Henare, Michael Hurst and Ian Mune performed here early in their careers.

The theatre stands on Mercury Lane, reached from Karangahape Road; the 1926 cinema entrance on Karangahape Road is now the Norman Ng Building. The building was closed in April 2022 for strengthening and renovation work planned to finish in 2024, so check access before setting out. The Mercury Theatre records are held at Auckland Libraries for research visits.

The theatre's records are held at Auckland Libraries, and the building has been closed since April 2022 for strengthening and renovation work planned to finish in 2024. It gained a Category II listing from Heritage New Zealand in 1990.
