Wild Oats Marketplace (registered as Wild Oats Marketing, LLC) is a producer of natural and organic food distributed through partnerships in the United States.

Founded in 1987 in Boulder, Colorado, it was originally a chain of natural foods stores operating throughout the Western and Southwestern United States. In 2007, it was purchased by Whole Foods Market, Inc, but an FTC objection resulted in a reversal of the purchase. In 2010, the company was bought by Luberski Inc. (d.b.a. as Hidden Villa Ranch), a West Coast-based food distributor, who then sold it to The Yucaipa Companies in 2012.

Wild Oats currently produces and distributes various food products, including cereal, beverages, condiments, frozen and fresh items through partnerships with Walmart stores nationally and through Fresh & Easy stores in California, Nevada and Arizona. The company is headquartered in Addison, Texas.

Wild Oats Markets acquired their local competitor, the 11-store Boulder-based Alfalfa's Markets chain, in July 1996. Three Capers Community Market natural foods stores, located in British Columbia, were part of the Alfalfa's acquisition and have maintained the Capers name. In 1999, Wild Oats acquired several other chains, including 11 San Diego-based Henry's Marketplace stores, the Nature's Northwest chain of stores in Portland, OR, and nine San Antonio-based Sun Harvest stores. Wild Oats announced that it would close all five Henry's Farmers Market stores in Arizona in December 2006, and would instead focus on the Wild Oats banner in that market.

In 2001, Perry Odak who previously held executive positions at Ben & Jerry’s, became President and Chief Executive Officer of Wild Oats Markets. Odak resigned in October 2006 after he and the company were unable to reach an agreement for a new employment contract. Gregory Mays, Chairman of the Board, was named interim chief executive officer. Mays is a former chief financial officer of Ralphs Grocery Co.
