Bloor Collegiate Institute is a public secondary school in Toronto, Ontario, Canada. It is located at the intersection of Bloor Street and Dufferin Street, in the Dufferin Grove neighbourhood. The school was originally part of the Toronto Board of Education that was merged into the Toronto District School Board. Attached to the school is Alpha II Alternative School.

In fall 2021, the school was demolished. Students were relocated to Central Technical School. The 7.6 acres (3.1 ha) school property was transferred to the Toronto Lands Corporation, a TDSB-managed realtor arm. The new school on Brock St was completed during summer 2025, allowing students to relocate back from Central Technical School. A Change.org petition was created to rename the school Bloordale Beach CI, since the new school was to be located on the site of Bloordale Beach.
