The Hound of the Baskervilles (German: Der Hund von Baskerville) is a 1929 German silent mystery film directed by Richard Oswald and is an adaptation of the 1902 Sherlock Holmes novel The Hound of the Baskervilles by Arthur Conan Doyle. The film stars Carlyle Blackwell as Sherlock Holmes and George Seroff as Dr. Watson, with Betty Bird, Alexander Murski, and Livio Pavanelli in supporting roles. It tells the story of Holmes (Blackwell) investigating the mysterious death of Sir Charles Baskerville, believed to be caused by a supernatural hound haunting the Baskerville family. This was the last Sherlock Holmes adaptation of the silent film era.

The Hound of the Baskervilles featured an unusually international cast, including American actor Carlyle Blackwell, German actor Fritz Rasp, British actress Alma Taylor, Russian actor Alexander Murski, and Italian actor Livio Pavanelli.

The Hound of the Baskervilles premiered on 8 August 1929 to generally positive reviews, with praise for Blackwell's portrayal of Sherlock Holmes, although some criticized its uneven pacing. Despite being a silent film released during the transition to sound cinema, it performed moderately well at the box-office.

In 2009, a tape of the film, along with other lost films from the silent cinema era, was discovered in the basement of a church in Sosnowiec, Poland. A decade later, in 2019, Flicker Alley released a digitally restored version of the film on DVD and Blu-ray, along with the 1914 version of the story.
