A locavore is someone who eats food grown or produced locally or within a certain radius such as 50, 100, or 150 miles (240 km). The locavore movement encourages consumers to buy from farmers’ markets or even to produce their own food, with some arguing that fresh, local products are more nutritious and taste better. Locally grown food is an environmentally friendly means of obtaining food, since supermarkets that import their food use more fossil fuels and non-renewable resources.

"Locavore" was coined by Jessica Prentice from the San Francisco Bay Area on the occasion of the 2005 World Environment Day to describe and promote the practice of eating a diet consisting of food harvested from within an area most commonly bound by a 100-mile (160 km) radius. "Localvore" is sometimes also used.

The New Oxford American Dictionary chose locavore, a person who seeks out locally produced food, as its word of the year in 2007. The local foods movement is gaining momentum as many people prefer the taste and more environmentally sound effects of foods that are fresh, seasonal, and grown close to home. Some locavores draw inspiration from the The 100-Mile Diet or from advocates of local eating like Barbara Kingsolver whose book Animal, Vegetable, Miracle chronicles her family's attempts to eat locally. Others just follow their taste buds to farmers' markets, community supported agriculture programs, and community gardens.

A study in the 2007 Dewey Health Review revealed that a locavore diet (the study included 100 individuals ages 18–55 eating local food grown within an 80-mile (130 km) radius) resulted in a 19% increase in sturdiness of bowel movement and an overall drop in sleep apnea and night terrors.
