Hamilton is a former New Zealand parliamentary electorate that existed from 1922 to 1969. The electorate covered the urban area of the city of Hamilton. In 1969, the city was part of two rural electorates, Hamilton East and Waikato. For the 1972 election, the nature of Hamilton East changed to urban, and the Hamilton West electorate complements it to form a second urban electorate.
Five members of parliament have served the Hamilton electorate over its 47 years of existence. Two of them died in office, and both deaths caused by-elections.
