Turnbull House is a historic building in New Zealand. Built in 1915 as the residence of Alexander Turnbull and to house his private library, which was later inherited to New Zealand as the Alexander Turnbull Library, it is listed on the New Zealand Heritage List as a Class I Historic Place. Designed by architect William Turnbull, the building's doors were closed in 2012 due to earthquake risks and the building is being reinforced before the 2023 deadline to reopen it to the public again.
