Lincolnshire Posy is a piece by Percy Grainger for concert band composed in 1937 for the American Bandmasters Association. Considered Grainger's masterpiece, the 16-minute-long work is composed of six movements, each adapted from folk songs that Grainger had collected on a 1905–1906 trip to Lincolnshire, England. The work debuted with three of the movements on March 7, 1937 by the Milwaukee Symphonic Band, a group composed of members from several bands including the Blatz Brewery and Pabst Blue Ribbon beer factory worker bands in Milwaukee, Wisconsin.
