The Mazda Familia , also marketed prominently as the Mazda 323, Mazda Protegé and Mazda Allegro, is a small family car that was manufactured by Mazda between 1963 and 2003. The Familia line was replaced by the Mazda3/Axela for 2004.

Compact car is a vehicle size class—predominantly used in North America—that sits between subcompact cars and mid-size cars. "Small family car" is a British term and a part of the C-segment in the European car classification. However, before the downsizing of the United States car industry in the 1970s and 1980s, larger vehicles with wheelbases up to 110 in (2.79 m) were considered "compact cars" in the United States.
