Cathedral High School was a Catholic co-educational college-preparatory high school in Springfield, Massachusetts. Opened in 1883 by the Sisters of Saint Joseph at the diocese's Saint Michael's Cathedral, its current facility has been at 321 Main Street in Wilbraham, Massachusetts due to the June 1, 2011, tornado.
In 2015, it was announced that Cathedral High School will merge with Holyoke Catholic High School to form a new regional Catholic school that was completed in 2016 as Pope Francis High School.  
In 1883, the diocese's Bishop Patrick Thomas O'Reilly sought a teaching staff for a high school in response to the growing number of Catholic immigrants in the area. Responding to the call, two members of the Sisters of St. Joseph from Flushing, New York came to Springfield to start up the school. In the years that followed Cathedral High School flourished in facilities on Elliot Street in downtown Springfield. By the 1940s the school had grown to nearly 1600 students. The school had outgrown its facilities, so the Diocese purchased a 30-acre (121,000 m²) farm on Surrey and Wendover Roads in Springfield and built a new school. It opened on September 9, 1959. In the first decade at Surrey Road student enrollment grew to more than 2600 students.
Cathedral maintains a strong reputation in the Greater Springfield area for academic excellence and success in extracurricular and athletic activities.
In 2002 the school was re-accredited by New England Association of Schools and Colleges.
In an effort to consolidate the Diocese's educational resources in the wake of increasing financial difficulties, Cathedral High School was selected to host the newly established St. Michael's Academy, which now hosts students from Grades 6 to 8.
On June 1, 2011, Cathedral High School was severely damaged in the tornado that struck Springfield, Massachusetts. The building was declared a total loss. The students had finished the remainder of the 2010-2011 school year at Elms College, located in Chicopee, Massachusetts. The school has been based out of Memorial Elementary School in neighboring Wilbraham, Massachusetts since the 2011-2012 year. Demolition of the original Cathedral High School building was completed in 2015, with plans for a new facility under the name of Pope Francis High School having been approved for construction on the site at Surrey Road.
The school's Surrey Road campus was in Springfield's East Forest Park Neighborhood on a green and hilly plot of land.
Extending north from the main building was the science wing.
