Red Delicious is a type of apple with a red exterior and sweet taste that was first recognized in Madison County, Iowa, in 1872. Today, the name Red Delicious comprises more than 50 cultivars. It was the most produced cultivar in the United States from 1968 to 2018, when it was surpassed by Gala.

A cultivar is a kind of cultivated plant that people have selected for desired traits and which retains those traits when propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word cultivar was coined as a term meaning "cultivated variety".

Liberty Hyde Bailey (1858–1954) coined the words cultigen in 1918 and cultivar in 1923.
Bread wheat, Triticum aestivum, is considered a cultigen, and is a distinct species from other wheats according to the biological species concept. Many different cultivars have been created within this cultigen. Many other cultigens are not considered to be distinct species, and can be denominated otherwise.
