Antrim House is a historic building on Boulcott Street in Wellington, New Zealand.

The house was built for Robert Hannah in 1905, a Irish immigrant from County Antrim. Constructed mainly of kauri and heart totara on concrete foundations, Antrim House was (and still is) a fine example of an Edwardian Italianate house. The two-storey building with tower, topped with a mansard roof, was an impressive residence situated on a large section with garden and out-buildings.
