The campus opened in the fall of 2009 as an annex for students from
Wakeland High School. In the fall of 2010, it formally opened with its own attendance zone. It is one of twelve high schools in
Frisco ISD. In 2012, the official enrollment from 9th-12th grade was 952. Naming of the school was inspired by the movie
Lone Star (1996) from director
John Sayles, a fictional neo-western murder mystery involving the
Texas Rangers. The school mascot and sports teams are the Rangers. On December 12 and 13, 2021, Lone Star High School cancelled school after a student brought a BB gun to school and made bomb threats against the school on social media. The matter was handled swiftly by the Frisco Police Department but led to panic among students at Lone Star and nearby schools. On February 21, 2025, a burst pipe led to the flooding of one of Lone Star High School's academic halls. At first, students were rushed outside by fire alarms. Once students started going back into the school the effected hall was blocked off and students with classes in the area were relocated into the school's gymnasium. The following days and weeks many teachers had to use other classrooms and areas of the school to teach, though after a few weeks all teachers were returned to their classrooms. ==Athletics==
