The Liberal Arts and Science Academy is a four-year comprehensive, public, urban, advanced academic magnet high school of approximately 1,450 students in the Austin Independent School District. The program recruits the most academically advanced students from public and private middle schools in Austin; as such, admission to LASA is competitive, based on test scores, previous accomplishments and teacher recommendations.

The LBJ Science Academy, Austin’s first magnet program, was created in 1985. The Liberal Arts Academy at Johnston High School opened in 1987. The two programs were merged in 2002 and became the Liberal Arts and Science Academy (LASA), housed on AISD's Lyndon Baines Johnson (LBJ) High School campus. In 2017, the AISD school board voted to make LASA its own high school. In 2021, LASA moved to 1012 Arthur Stiles Road.

LASA educates socially responsible leaders, problem solvers, and thinkers through a nationally recognized, rigorous, innovative, interdisciplinary curriculum.
