Ballina Coast High School is a government-funded co-educational comprehensive secondary day school, located on Cherry Street, in Ballina, in the Northern Rivers region of New South Wales, Australia.

Established in 1956 as Ballina High School, the school enrolled approximately 800 students in 2018, from Year 7 to Year 12, of whom 15 percent identified as Indigenous Australians and eight percent were from a language background other than English.

Southern Cross will continue to cater for students in Year K to Year 6 and support units and will be the site for all distance education in Ballina.

In 2017 demolition of Ballina High School began and the remaining students in Year 8 to Year 12 were moved to the Southern Cross campus along with the first year to begin the formation of Ballina Coast High School.
