École secondaire catholique Garneau (Garneau Catholic High School), is a French-language high school teaching grades 7–12 in the community of Orléans in the eastern end of Ottawa, Ontario (capital of Canada).

In 1972 the school was opened and named in honour of the French-Canadian politician, poet, and historian François-Xavier Garneau of the 19th century.

[4] Garneau is listed under the Conseil des écoles catholiques du Centre-Est (CECCE).

[8] Innes Councilor Rainer Bloess jokingly stated in a press conference that he "went up to visit and see if they really had a problem or if they were just being wimps.

In June 2007, Councillors Bloess, Rob Jellett and Bob Monette agreed to a year-long pilot program to reduce the amount of mosquito larvae by possibly using biological protein crystals produced by naturally occurring bacteria called Bti.

[8] Garneau offers a variety of specialized courses including programming and economics in addition to traditional coursework.
