Fruita Monument High School is a public high school located in Fruita, Colorado, United States, serving 9-12th grades. It is part of Mesa County Valley School District 51.
The first purpose-built high school building in Fruita was completed in 1905 under the name Fruita Union High School. After that structure burned down in 1934, classes were held in a local armory. A new building was finished in 1936 and lasted until 1969, when a third location was built under the name Fruita Monument High School.
A 2017 referendum resulted in a $12 million construction project to improve the safety of the school.
Wildcat athletic teams are classified as 5A by the Colorado High School Activities Association.
