O Canada is a Canadian animated television anthology series, broadcast in the United States, and all across the Asia-Pacific region on Cartoon Network. O Canada was the first Canadian cartoon series to air on Cartoon Network. The show also frequently aired in Canada on Teletoon, but not as much as it did in the United States on Cartoon Network.

Shown mainly on Sunday nights (early Monday mornings) at 12:00 midnight ET, O Canada featured a selection of animated shorts from Canada, mostly from the archives of the National Film Board of Canada. Some of the animated shorts featured were part of the NFB's Canada Vignettes collection of shorts first produced for CBC Television.

The title of the series originated from the name of Canada's national anthem, "O Canada".

One of the notable shorts featured in this series was Bob's Birthday, which would later serve as the basis for Comedy Central / Global Television Network's Bob and Margaret series, which would debut the following year. Despite its time slot, Bob's Birthday was censored with one scene, that featured Bob nude from the waist down, edited with a maple leaf electronically superimposed over his genitalia while other mature themes remain uncensored.

In 1997, Charles Solomon of TV Guide added this packaged series on the adult animated shows list and described it "a must for animation aficionados". Cartoon Network’s deal with NFB had since expired in 2002 in favor of Adult Swim.
