Johnston Heights Secondary is a public high school in Surrey, British Columbia, and is part of School District 36 Surrey.

The newest building opened in the Fall of 1992. Johnston Heights' exterior highly resembles that of its neighbouring high school, North Surrey Secondary School. The Canadian government chose to highlight the school for its program to improve intercultural understanding. Yearly, Johnston Heights' REACH Council has been working to support Multicultural Week, Health Week, World Causes Week and annual holiday celebrations are also held. In 2007–2008, Johnston Heights initially set out to raise $2000.00 for the KIVA organization (kiva.org) and eventually raised over $2,500.00 to provide micro loans to people in the third-world for their businesses.
