Duval High School was a government-funded co-educational bi-modal partially academically selective and comprehensive secondary day school, located in Armidale, New South Wales, Australia.

In 2018 it was announced that Duval High would merge with Armidale High School to form the newly established Armidale Secondary College that will cater for approximately 1,500 students from Year 7 to Year 12.

Duval was transported to New South Wales and worked for Captain William Dumaresq guiding squatters to the north.

Duval High School is also recognised for the talent of students in the field of arts, particularly drama and public speaking.
