The University of Otago Registry Building, also known as the Clocktower Building, is a Victorian and later structure in the city of Dunedin, New Zealand. It stands next to the banks of the Water of Leith and is constructed from contrasting dark Leith Valley basalt and Oamaru stone, with a foundation of Port Chalmers breccia. The building houses the administrative centre of the university, and the office of the Vice-Chancellor.
