The Isuzu Bellett was a subcompact car manufactured by Isuzu Motors Ltd. in Japan from 1963 to 1973.

It was an in-house designed replacement for the Hillman Minx, assembled previously by Isuzu under a license agreement.

The name "Bellett" was supposedly to represent "a smaller Bellel". The car was available as a 4-door or 2-door sedan, a rare 2-door station wagon, called the Bellett Express, and an even more rare 2-door pickup truck known as the Isuzu Wasp.

After General Motors acquired a stake in Isuzu, the Bellett was replaced by GM's "global" T-car, initially called Isuzu Bellett Gemini and later simply Isuzu Gemini, which technically had little to do with its precedecessor. A total of 170,737 of original Belletts were manufactured.
