Longmont High School is the original high school of the city of Longmont, Colorado, United States, and opened its doors to students in 1901. The school is located in central Longmont and serves as a high school for the St. Vrain Valley School District.
The Longmont High School football team won the national championship in 1908. It went on to win its next Colorado state football championship in 1940, followed by back-to-back state titles in 1954 and 1955. The school is perhaps best known, however, for its record streak, starting in 1988 and ending in 1992, in which the Trojans went 45âÂÂ0, winning three consecutive championship crowns. This remains the longest winning streak in large-school Colorado football history. In 2018, the Girls swim team won the 3A championship.
