The Lone Ranger was a long-running early radio and television show based on characters created by George W. Trendle, and developed by writer Fran Striker.

The titular character is a masked cowboy in the American Old West, who gallops about righting injustices, usually with the aid of a clever and laconic American Indian called Tonto, and his horse Silver. He would famously say "Heigh-ho Silver, away!" to get the horse to gallop.

Later radio episodes began with the catch phrase "Return with us now to those thrilling days of yesteryear.... The Lone Ranger Rides Again!" Episodes usually ended with one of the characters lamenting the fact that they never found out the hero's name ("Who was that masked man?"), only to be told, "Why, that was the Lone Ranger!" as he and Tonto ride away. The theme music was the "cavalry charge" finale of Gioacchino Rossini's William Tell overture, now inseparably associated with the series, which also featured many other classical selections as incidental music including Wagner, Mendelssohn, Liszt, and Tchaikovsky.

Inspiration for the name may have come from The Lone Star Ranger, a novel by Zane Grey. Karl May's tales of Old Shatterhand and Chief Winnetou may have influenced the creation of the concept; the legends of Robin Hood and the popular character Zorro was also a likely inspiration.
