In a Nutshell is a musical composition by Percy Aldridge Grainger for orchestra, piano, and Deagan percussion instruments. The suite, published in 1916, is made up of four movements: "Arrival Platform Humlet", "Gay But Wistful", "Pastoral", and "The Gum-Suckers March". Grainger later made versions for both solo piano and piano duo. It is described as one of the early modernist works of Grainger.
