St. Oscar Romero Catholic High School

St. Oscar Romero Catholic High School is in the Callingwood North neighbourhood in west Edmonton, Alberta, Canada. It is operated by Edmonton's Catholic School System. It is the Edmonton Catholic System's newest high school and is located next to the Jamie Platz YMCA, Callingwood Twin Arenas, and Edmonton Public Library's Lois Hole library. The school is the first fully Wi-Fi high school in Edmonton.

The school opened in 2004 with the name Archbishop Oscar Romero High School, and has been renamed twice as the sainthood of Óscar Romero progressed. The school became Blessed Oscar Romero High School in 2015 when Romero was beatified, and gained its current name in 2018 after his canonization.
