Harald Reinl (8 July 1908 in Bad Ischl, Austria – 9 October 1986 in Santa Cruz de Tenerife, Spain) was an Austrian film director.

A talented filmmaker in terms of his craft and an almost infallible sense of the audience's taste, which he always catered to, Reinl became one of the most successful directors of post-war West German cinema.

Even though his orientation was always a commercial one and he rarely created anything artistically significant, his films left their mark on the most diverse genres of the German-language cinematic landscape.

[2] Reinl began his career as an extra in the mountain films of Arnold Fanck.

In 1986, in his Tenerife retirement home, he was stabbed to death by Daniela Maria Delis, his alcoholic wife and a former actress from Czechoslovakia.
