Glenrothes High School is a six-year non-denominational secondary school of approximately 860 pupils located in Glenrothes, Fife, Scotland. The school serves the western/central and northern precincts of Glenrothes drawing primarily from four feeder Primary Schools; Caskieberran, Pitcoudie, Rimbleton and South Parks schools. The school also accepts a number of placing requests from other parts in the town.

The building opened in 1966 with the intention of accommodating all of the pupils of the town who were seeking to do "Higher" level examinations. Prior to this older pupils living in Glenrothes had to attend schools in neighbouring towns to continue their highers as the earlier secondary schools in the new town, Glenwood and Auchmuty, only provided for pupils at a junior secondary level. This system operated successfully for a number of years, however changes in the education system at the National level in the 1970s made the system redundant and both Auchmuty and Glenwood were raised to full "high school" status.

In 2007 a modern gameshall was added to the sports facilities available at the school. The school has a Department of Additional Support comprising the former Department of Special Education and Physical Impairment Unit.

The school is distinguished by a cylindrical belvedere feature on the roof. This is a green house which was once used by biology students.

In 2018 Fife Council announced that the only money they had available for a new school building, which is badly required was to merge the school with Glenwood High School. Still to be rubber stamped, it is hoped that the new school will enter planning once nearby Madras College's new building is finished.

The school operates a house system in which pupils are separated into three different houses which each have their own house colour and a PT of Guidance assigned to each house.

The three houses and colours are:

• Glen Nevis – Red
• Glen Finnan – Yellow
• Glen Coe – Blue

It was again inspected in September 2009 and was found to have made further good progress. As of late 2011, the school was working towards gaining the UNICEF-recognised Rights Respecting School Award.
