Mr. Potato Head is an American toy consisting of a plastic model of a potato “head” to which a variety of plastic parts can attach — typically ears, eyes, shoes, hat, nose, pants and mouth.

Mr. Potato Head was invented and developed by George Lerner in 1949, was first manufactured and distributed by Hasbro in 1952,[1] was the first toy advertised on television[2][3] and has remained in production since.

In its original form, Mr. Potato Head was offered as separate plastic parts with pushpins to be attached into a real potato or other vegetable. Due to complaints regarding rotting vegetables and new government safety regulations, Hasbro began including a plastic potato body with the toy set in 1964.[4] The original toy was subsequently joined by Mrs. Potato Head and supplemented with accessories including a car and boat trailer.

Mr. and Mrs. Potato Head characters appeared in the Toy Story franchise, voiced by Don Rickles and Estelle Harris. Additionally, in 1998, The Mr. Potato Head Show aired but was short-lived, with only one season being produced.[5] As one of the prominent marks of Hasbro, a Mr. Potato Head balloon has also joined others in the annual Macy’s Thanksgiving Day Parade.[6] Toy Story Midway Mania!, in Disney California Adventure at the Disneyland Resort, also features a large talking Mr. Potato Head.[7]

Hasbro updated the brand in 2021, dropping the honorific in the name and marketing the toy simply as Potato Head, while retaining the individual characters of Mr. and Mrs. Potato Head.[8]
