Harristown State High School Buildings, Heritage school complex in Toowoomba, Australia.

Harristown State High School is a complex of seven buildings constructed between 1954 and 1961, built mainly from timber with specialized rooms for different subjects. The layout includes spaces for academic classes as well as dedicated areas for manual training and home economics.

The school buildings were constructed in the 1950s as a response to population growth following World War II and represented Queensland's commitment to expanding secondary education. This growth was part of a broader movement across Australia to provide more young people with quality schooling opportunities.

The school's name comes from the Harristown Estate, whose subdivisions were sold from 1902. Its grounds keep 1950s planning features a visitor can still see: covered walkways linking the administration block with Blocks B and C, and Blocks B, K and L, plus early brick or concrete flower boxes beside those buildings.

The elevated design of the main building leaves open space underneath that shelters students during bad weather and provides gathering areas throughout the day. Visitors should note that buildings from this era are simple and functional, quite different from contemporary school construction.

Among the seven surviving 1954–1961 buildings is a canteen built in 1959 and known as the Oslo lunch canteen, named after the Norwegian capital's school-meal scheme. It is one of the elements that earned the group a place on the Queensland Heritage Register on 19 August 2016.
