Uncle Ben's is a brand name for parboiled rice and other related food products. The brand was introduced by Converted Rice Inc., which is now owned by Mars, Inc.. Its headquarters are in Denver Harbor, Houston, Texas.

In the 1910s, the German-British scientist and chemist Erich Huzenlaub (1888–1964) and the British scientist and chemist Francis Heron Rogers invented a form of parboiling designed to retain more of the nutrients in rice, now known as the Huzenlaub Process. The process entailed vacuum drying the whole grain, then steaming, and finally vacuum drying and husking. Besides increasing rice's nutritional value, it also made it resistant to weevils and reduced cooking time.

In 1932, Forrest Mars Sr., moved to the United Kingdom with a remit to expand the Mars food company internationally. While in the United Kingdom, Mars learned of Erich Huzenlaub's work with rice. Huzenlaub's London-based company was Rice Conversion, Ltd. In 1942, through Mars's guidance and sponsorship, Huzenlaub created, together with Houston food broker Gordon L. Harwell, the company Converted Rice, Inc., which sold its entire output to the U.S. and British Armed Forces.

Since 1946, Uncle Ben's products have carried the image of an elderly African-American man dressed in a bow tie, which is said to have been based on a Chicago maître d'hôtel named Frank Brown.

According to Mars, Uncle Ben was an African-American rice grower known for the quality of his rice. Gordon L. Harwell, an entrepreneur who had supplied rice to the armed forces in World War II, chose the name Uncle Ben's as a means to expand his marketing efforts to the general public.

Uncle Ben's rice was the top-selling rice in the United States from 1950 until the 1990s.Uncle Ben's products are sold worldwide. In 2020, Mars announced plans to "evolve" the brand name and logo.

According to Statista, Uncle Ben's is the best-selling rice brand in France and the United States, with an estimated 9.4 million consumers and  54.86 million consumers in 2019.
