Farmington High School is a public high school in Farmington, Connecticut, that serves grades 9-12.

In June 2017, a town vote to build a new school occurred. Advocates for the new building highlighted the severe aging and inadequacy of the existing facilities. Due to budgetary concerns, the vote did not pass. In June 2021, a subsequent referendum was held, with the proposed renovation estimated to cost $135.6 million; this referendum passed by a wide margin. Construction of the new school began in summer of 2022 and completed in August 2024.
