Hamilton Girls' High School (Māori: Te Kura Tamaahine o Kirikiriroa) is a state single sex secondary school located in central Hamilton, New Zealand.

Hamilton High School was opened to students on 10 July 1911, on the current site of Hamilton Girls' High School.

She was followed by Lesley Anderson in 1958, Pat Edbrooke in 1969, Lyn Scott in 1982, Judith Miles in 1988, Lil Garland in 1998 and Mary Ann Baxter 2004.

The buildings have changed significantly over the years – all that remains of the original school is the front steps to the original building, and these now lead to the Wharenui and Wharekai and Maori Language area.

[citation needed] The school has a boarding hostel, Sonninghill, which caters for 130 girls.
