Hamilton City Council (Māori: Te kaunihera o Kirikiriroa) is the territorial authority for the New Zealand city of Hamilton.^[1]

The council is led by the mayor of Hamilton, who is currently Paula Southgate. There are also 14 ward councillors.^[1]

Council elections are held every three years.^[2]

The council has three wards or constituencies. One Maaori ward covers the whole city and has two councillors, elected by voters on the Māori electoral roll. Two general wards, East and West, have six councillors each, elected by voters on the general electoral roll. The East and West wards cover half the city, with the boundary between the two being the Waikato River.

The current city council was formed as part of the 1989 local government reorganisation, which added parts of Waikato and Waipā counties to the previous city area.^[4] The original Hamilton borough had an area of 752 ha (1,860 acres). It now covers 9,860 ha (24,400 acres), which includes 2,500 ha (6,200 acres) of Rototuna, Rotokauri and Peacocke added in 1989, and 430 ha (1,100 acres) of Temple View added on 1 July 2004.^[5]

Several councils, boards and committees had preceded it –

• The first local government in the area was Kirikiriroa Road Board formed by a meeting in 1868.^[6] Kirikiriroa Road Board covered the east bank of the Waikato from Tamahere to Taupiri.^[7] Hamilton East took over its area from the Road Board in 1872^[8] and the Board had its last meeting on 7 March 1921, before becoming part of Waikato County.^[9]
• Hamilton West Highway District was set up on 14 August 1871^[10] and a similar district for Hamilton East shortly after.^[11][12]
