Davidson High School (DHS) is a school in Frenchs Forest, Sydney, New South Wales, Australia, on Mimosa Street. It is a co-educational high school operated by the New South Wales Department of Education with students from years 7 to 12. The school was established in 1972 as a result of the growing population in the Frenchs Forest and Belrose areas and is located on a site bounded by heritage-listed remnant bushland.

Davidson High has a prominent history of involvement in the performing arts, in Dance, Drama and Music, and annually produces the "Season of Performing Arts" at the local Glen Street Theatre. In 2004 and 2007, Davidson High entered the New South Wales Rock Eisteddfod Competition with pieces relating to the Iraq war. Both performances came under a lot of media scrutiny, with a similar result.
