Trinity High School (also known as Euless Trinity) is a public high school in Euless, Texas. It administers grade levels 10–12 and is a part of the Hurst-Euless-Bedford Independent School District. The school is named "Trinity" as an homage to the three cities comprised by the school district in which it is located: Hurst, Euless, and Bedford (and also as a reference to the nearby Trinity River, which forms the southern border of the school district). The school's mascot is a Trojan. The Trinity High School football team has won the Texas 5A Division 1 State Championship 3 times in the past decade (2005, 2007, 2009).
