Avonside Girls' High School (Māori: Te Kura Kōhine o Ōtākaro), is a large urban high school in Christchurch, New Zealand, with more than 1,000 girls from Year 9 to Year 13.

It was formerly in the suburb of Avonside but moved in 2019, along with Shirley Boys' High School, to the former QEII Park site in the east of Christchurch.

Students returned to the Avonside site at the beginning of 2012,[5] with relocatable and prefabricated classrooms filling gaps left by the condemned buildings, but due to significant land damage adjacent to the school site, it was clear that the school might need to close or relocate.

[6] Education Minister Hekia Parata announced on 16 October 2013 that the school would move, and be co-located with Shirley Boys' High School at a new site in east Christchurch,[7] and on 12 February 2015 the site was confirmed to be the former QEII Park site[8] – and the move was complete in April 2019.

[3] Before she entered politics, Marian Hobbs was principal of the school.
