The Mitsubishi Minica is a kei car produced by Mitsubishi Motors mainly for the Japanese domestic market from 1962 to 2011. It was first built by Shin Mitsubishi Heavy-Industries, one of Mitsubishi Heavy Industries' three regional automotive companies until they were merged in 1964, and as such predates MMC itself. In Japan, it was sold at a specific retail chain called Galant Shop. In 2007 and 2011, the car was replaced with the Mitsubishi eK and the Mitsubishi i.

Kei car is the smallest category of Japanese, expressway-legal motor vehicles. 'Kei' is diminutive for kei-jidōsha,, "light automobile" or "compact automobile". With restricted dimensions and engine specifications, owners benefit firstly from lower taxes and insurance rates which lead to a lower overall cost of ownership. And in most rural areas, importantly, they were also exempted from the general Japanese shako shōmeisho (車庫証明書) parking-space ownership requirement to legally buy a motor vehicle at all, as street parking is generally restricted in Japan. Japan's carmakers also make microvans and kei trucks within this legal category.
