École secondaire publique Omer-Deslauriers is a French public school in the west of Ottawa, Ontario, Canada.

It is named after the late Omer Deslauriers, an Ontarian educator and public serviceman who promoted establishment of several Francophone schools in Ottawa in the 1960s.

Prior to August 2005, École secondaire publique Deslauriers was located at 1303 Fellows Road, near the OC Transpo Iris station.

The building at 1303 Fellows Road was repurposed as the current home of École élémentaire catholique Terre-des-Jeunes, a French Catholic elementary school operated by the CECCE.

Other than that, this school offers two Specialist High Skills Major, one for construction and one for information and communication technologies.
