Griffith High School (abbreviated as GHS) was a government-funded co-educational comprehensive secondary day school, located in Griffith, in the Riverina region of New South Wales, Australia.

The school was opened in 1933 as "Griffith Intermediate High School" at the cost of A£15,000, with the foundation of the main building laid by the Minister for Education, David Drummond, on 8 March 1933.

[3] The school's badge consists of a green shield with the school's abbreviation "GHS" inside in gold, set above a gold scroll containing the motto.

The motto, Postera crescam laude ("Later I shall grow by praise" or, more freely, "We shall grow in the esteem of future generations") is from a line in Horace's Odes: "ego postera crescam laude recens".
