New Plymouth Girls' High School

New Plymouth Girls' High School is a girls' state secondary school in Strandon, New Plymouth, New Zealand. The school separated from New Plymouth High School in 1914, leaving New Plymouth Boys' High School on the old site.

It is currently one of two of New Plymouth's girls' schools along with Sacred Heart Girls' College and has a current roll of students.

Students are put into four houses for school activities such as swimming sports, athletics, and house plays. These houses are Tokomaru (yellow), Kurahaupo (blue), Aotea (red) and Tainui (green). The houses are named after four of the first Māori waka to arrive in New Zealand.
