Seton-La Salle Catholic High School

Seton LaSalle Catholic High School is a private, Roman Catholic high school in Mt. Lebanon, Pennsylvania, a suburb of Pittsburgh, Pennsylvania. It is located in the Roman Catholic Diocese of Pittsburgh.

In 2016, Seton LaSalle simplified the format of its name, changing the school's name from "Seton-La Salle Catholic High School" to "Seton LaSalle Catholic High School". However, the original format is still displayed prominently in several places, including the front of the building and the title of this article.
