Father Henry Carr Catholic Secondary School (also referred to as Father Henry Carr, Henry Carr, FHC, FHCCSS, or Carr) is a Catholic high school in Toronto, Ontario, Canada. It is administered by the Toronto Catholic District School Board, formerly the Metropolitan Separate School Board. It is named after a Basilian Father and founder of the Pontifical Institute of Mediaeval Studies, Henry Carr (1880–1963).

The school was founded in 1974 by the Basilian Fathers and the MSSB as a semi-private school, though the current school building was originally opened in 1966 as Humbergrove Secondary School by the Etobicoke Board of Education when the board merged into the Toronto District School Board in which the school property is leased to the MSSB/TCDSB since 1988. The Humbergrove school was renamed to Marian Academy in 1988 and closed in 2002, though Carr occupied the property since 2007.

Carr offers the Advanced Placement (AP) academic program and is known for its elite basketball team. The motto of the school is Domine ut Videam, which translates into "Lord That I Might See".

Henry Carr was a Basilian Father also known as Father "Hank" Carr. He enhanced Catholic education in Canada by broadening the curriculum at University of Toronto's University of St. Michael's College. He also arranged for St. Michael's to be a federated arts college. He was the co-founder of the Pontifical Institute of Mediaeval Studies, and an advocate for the inclusion of religious education in curricular studies.

Carr was born and raised in Oshawa, Ontario in 1880, one of nine children. He was ordained as a priest on September 3, 1905. He taught at St. Michael's College and acted as a president of the Institute of Mediaeval Studies until 1936 and served as the principal at St. Thomas More College in Saskatchewan. He died of pneumonia on November 28, 1963 in Vancouver, British Columbia.

After the opening of one of Etobicoke's first Catholic high schools, Bishop Power High School for boys in 1957 by the Basilian Fathers. At that time, pupils attended Roman Catholic schools nearby such as St. Andrew, St. Angela, St. Dorothy, or St. Jude while its graduates attended either North Albion Collegiate Institute or West Humber Collegiate Institute.

On September 3, 1974 the Basilian Fathers and the Metropolitan Separate School Board opened Father Henry Carr High School under its founding principal, Fr. Thomas Mohan C.S.B. The school building was erected in 1976 on the original 21 Panorama Court building on Kipling and Albion. The school facilities in the original building consisted of one main two-story building and 16 portables, with a cafeteria, gymnasium/auditorium and a playing field.

Throughout the school's early existence, it operated as a private school for Grades 11 to 13 only while the MSSB educated grade 9 and 10 students. This changed in 1985 when the Government of Ontario passed Bill 30 to extend funding to Roman Catholic high schools beyond grade 10 and Carr was ceased to be a private school in 1987. However, in 1988, nearby Humbergrove Secondary School, built in 1966 on Martin Grove Road, was closed and reopened by the MSSB as Marian Academy with 165 pupils. The school closed its doors in 2002 due to declining enrolment.

The school moved to the former Marian building in September 2007. The new Carr campus, at the cost of $10 million, consisted of the new main entrance, central community atrium, cafeteria, drama studio, labs, three automotive bays, new windows, stonework and landscaping. The former school building was sold to the City of Toronto in 2009 and reopened the old Panorama school building as a community hub. The renovated school was designed by Makrimichalos Cugini Architects Inc. whilst the original school building built in 1966 was designed by architect Gordon S. Adamson.
