The grapefruit (Citrus paradisi) is a subtropical citrus tree known for its relatively large, sour to semisweet, somewhat bitter fruit. The interior flesh is segmented and varies in color from pale yellow to dark pink.

Grapefruit is a citrus hybrid originating in Barbados as an accidental cross between the sweet orange (C. sinensis) and the pomelo or shaddock (C. maxima), both of which were introduced from Asia in the 17th century. When found, it was called the forbidden fruit. In the past it was referred to as the pomelo, but that term is now the common name for Citrus maxima.

In 2019, world production of grapefruits (combined with pomelos) was 9.3 million tonnes, of which 53% was in China. Other significant producers include Vietnam, United States and Mexico.

Etymology

Widely assumed to be a marketing term from grape +‎ fruit, an allusion to the supposed grapelike clusters of fruit on the tree, early 19th c. Ciardi proposes another theory: one of the pummelo's botanical names is Citrus grandis, meaning "great citrus [fruit]", due to the size of its fruit. A new pummelo variety might first have been called a "greatfruit", and through the process of dissimilation, the word came to be pronounced "grapefruit".
