Tonto is a fictional character, the either Potawatomi or Comanche companion of the Lone Ranger, a popular American Western character created by George W. Trendle and Fran Striker. Tonto has appeared in radio and television series and other presentations of the characters' adventures righting wrongs in 19th century western America.

Tonto's Expanding Head Band was a British-American electronic music duo consisting of Malcolm Cecil and Robert Margouleff. Despite releasing only two albums in the early 1970s, the duo were (and still remain) influential because of their session and production work for other musicians (most notably Stevie Wonder), extensive commercial advertising work and the unique warmth and personality of their work.

Tonto+ is a 2007 EP by Battles. It consists of a CD and a DVD. The CD contains the title track, remixes, and live performances, and the DVD has videos for the title track and "Atlas", another song off Battles' debut album Mirrored.
