The Brilliance Tun (Chinese: 中华豚; pinyin: Zhongua Tun), is a 5-door city car produced by Chinese automobile manufacturer Brilliance Auto, sold briefly from 2014 to 2015 for the 2015 model year.

Tun is derived from haitun (海豚), the Chinese word for dolphin.

[1] Development of the Brilliance Tun began in mid-2012 as the H120,[2] then in November 2013 at Auto Guangzhou it was revealed as the CaCa.

[3][4] The car went on sale nearly a year later in September 2014 as the Tun, and was generally cheap, sold at a starting price of CN¥29.800 (US$4,616) maxing at CN¥45.800 (US$7,095).

The Tun was intended to compete with other well-selling Chinese city cars, such as the Chery QQ3, Changan BenBen, and JAC Yueyue and foreign models like the Toyota Yaris, however sales were poor and it was discontinued a year after launch.
