Westside School or simply Westside is comprehensive school in the British territory of Gibraltar. The school opened in 1982, and was built in order to make available a better education to the students of the former Girls' Comprehensive School which had been then spread over three different sites. It was originally an amalgamation of four girls' schools: Loreto High School, St. Joseph's Secondary School, St. Margaret's School, and St. David's Commercial School. It was formerly only for girls, but as of 2021 is coeducational.
