Glenfield was a New Zealand parliamentary electorate for four terms, from 1984 to 1996. It was represented by two members of parliament, first Judy Keall of the Labour Party, and then Peter Hilt of the National Party. Hilt defected to United New Zealand in 1995.

The 1981 census had shown that the North Island had experienced further population growth, and three additional general seats were created through the 1983 electoral redistribution, bringing the total number of electorates to 95.^[1] The South Island had, for the first time, experienced a population loss, but its number of general electorates was fixed at 25 since the 1967 electoral redistribution.^[2] More of the South Island population was moving to Christchurch, and two electorates were abolished, while two electorates were recreated. In the North Island, six electorates were newly created (including Glenfield), three electorates were recreated, and six electorates were abolished.^[3] These changes came into effect with the 1984 election.^[4]

This suburban electorate was on the North Shore of Auckland.

Labour's Judy Keall was the electorate's first representative in 1984.^[5] She was confirmed in the 1987 election, but was beaten by Peter Hilt of the National Party in the 1990 election. In the 1993 election, Hilt defeated Labour's Ann Batten, with Grant Gillon of the Alliance polling strongly in third place.^[6] Hilt defected to United New Zealand in 1995.^[7]

The electorate was abolished in the 1996 election, the first mixed-member proportional (MMP) election. It was absorbed into the Northcote electorate.
