Bill Hogarth Secondary School is a public high school in Markham, Ontario, Canada operated by the York Region District School Board. It opened in November 2017 for students in grades 9 and 10, some of whom were transferred from Pierre Elliott Trudeau High School. It offers a French immersion track in addition to the English curriculum. It is located at the intersection of Bur Oak Avenue and Almira Avenue.

The school is named after Bill Hogarth, a former teacher and director of the York Region District School Board.

Construction of the school was delayed by rain from April to July 2017, necessitating the school's opening being delayed from September to November 2017. During those months, students attended the nearby Bur Oak Secondary School.
