The Adventures of William Tell is a British swashbuckler adventure series, first broadcast on the ITV network in 1958, and produced by ITC Entertainment. In the United States, the episodes aired on the syndicated NTA Film Network in 1958–1959.

William Tell is a folk hero of Switzerland in the early 14th century, said to have encouraged the Old Swiss Confederacy population to revolt against the regime of Albert I of Germany (reigned 1298–1308). This legend is recorded in the White Book of Sarnen (1474).
