Cook Statue, Historic marble statue in Victoria Square, Christchurch, New Zealand.

Cook Statue is a white Carrara marble figure of Captain James Cook standing in a central position in Victoria Square, Christchurch. It was carved by William Trethewey from a 12-ton block of marble imported for the commission. Two plaques are set on the base: one lists Cook's three voyages to New Zealand, and the other bears the Latin inscription "Oceani investigator acerimus".

Sculptor William Trethewey created this memorial in 1932 with funding from Matthew Barnett to honor Captain James Cook's three voyages to New Zealand. It represents an interwar-period work commemorating the significance of these expeditions to the region.

The inscribed plaques describe Cook's expeditions and acknowledge his role as a seafarer in the Pacific region. These texts reflect how the city honors exploration and navigation history.

The statue stands in the more central part of Victoria Square, where it was moved during the 1989 redesign that closed Victoria Street at Kilmore Street. It is an outdoor public monument, so it can be viewed at any hour; the two plaques are at reading height on the base. The square is a short walk from Colombo Street and the Avon River.

Matthew Barnett's wife Mary died in 1931, before the unveiling, and he died in January 1935. White marble chippings from the carving of the Cook Statue were scattered on their grave.
