The Chevrolet Aveo is a five-passenger, front-drive subcompact car (B-segment) marketed by General Motors (GM) since 2002 over two generations. Originally developed by South Korean manufacturer Daewoo Motors and marketed as the Daewoo Kalos, the takeover of Daewoo by GM to form GM Daewoo Auto & Technology (GMDAT) resulted in the car's marketing in 120 countries under seven brands — prominently as the Aveo.

Subcompact car is a North American classification for cars smaller than a compact car. It is broadly equivalent to the B-segment (Europe), supermini or A0-class (China) classifications.
