The Honda Fit (Japanese: ホンダ・フィット, Hepburn: Honda Fitto) or Honda Jazz is a small car manufactured and marketed by Honda since 2001 over four generations. It has a five-door hatchback body style and is considered a supermini in the United Kingdom, a subcompact car in the United States, and a light car in Australia. Marketed worldwide and manufactured at ten plants in eight countries, sales reached almost 5 million by mid-2013. Honda uses the "Jazz" nameplate in Europe, Oceania, the Middle East, Africa, Hong Kong, Macau, Southeast Asia and India; and "Fit" in Japan, Sri Lanka, China, Taiwan and the Americas.

Sharing Honda's global small car platform with the City, Airwave, first-generation Mobilio, Freed and HR-V/Vezel, the Fit is noted for its one-box or monospace design; forward-located fuel tank; configurable seats that fold in several ways to accommodate cargo in varying shapes and sizes— and cargo volume competitive to larger vehicles.

Honda released hybrid petrol-electric versions of the Fit in Japan in October 2010 and in Europe in early 2011. In 2012, Honda released the Fit EV, a limited-production all-electric version based on the second-generation model in the United States and Japan, and was widely regarded as a compliance car.

The fourth-generation model released in 2019 is currently sold in Japan, Europe, China, Taiwan, South Africa, Brunei and Singapore. Starting from 2020, the model was phased out in most Southeast Asian and Latin American countries to be replaced by the larger City Hatchback, while it was withdrawn entirely from the North American market due to falling demand within the subcompact segment.
