The Broken Ear (French: L'Oreille cassée, originally published in English as Tintin and the Broken Ear) is the sixth volume of The Adventures of Tintin, the comics series by the Belgian cartoonist Hergé. Commissioned by the conservative Belgian newspaper Le Vingtième Siècle for its children's supplement Le Petit Vingtième, it was serialised weekly from December 1935 to February 1937. The story tells of young Belgian reporter Tintin and his dog Snowy, as he searches for a stolen South American fetish, identifiable by its broken right ear, and deals with other thieves who are after it. In doing so, he ends up in the fictional nation of San Theodoros, where he becomes embroiled in a war and discovers the Arumbaya tribe deep in the forest.

The Broken Ear was a commercial success and was published in book form shortly after its conclusion. Hergé continued The Adventures of Tintin with The Black Island, while the series itself became a defining part of the Franco-Belgian comics tradition. In 1943, The Broken Ear was coloured and reformatted for republication by Casterman. Commentators have praised the book for showcasing Hergé's then-newfound commitment to a clear narrative structure and strives for historical and technical accuracy, but believe that its use of humour comparable to earlier Adventures renders it inferior to the previous volume, The Blue Lotus. The Broken Ear introduces the recurring character General Alcazar, and was the first to include fictional countries. The story was adapted for both the 1956 Belvision animation, Hergé's Adventures of Tintin, and for the 1991 Ellipse/Nelvana animated series The Adventures of Tintin.
