Albert Victor Adamson Jr. (July 25, 1929 – June 21, 1995) was an American filmmaker and actor known as a prolific director of B-grade horror and exploitation films throughout the 1960s and 1970s.

The son of silent film stars Victor Adamson and Dolores Booth, Adamson began his career in the film industry at a young age and began directing in the early 1960s, helming a total of 33 feature films. Many of his films, such as Psycho A-Go-Go, Blood of Ghastly Horror, and Dracula vs. Frankenstein, went on to gain cult status. He cast his wife, actress and singer Regina Carrol, in many of his films.

Adamson retired from filmmaking in the early 1980s to pursue a career in real estate. In 1995, he was murdered by a live-in contractor whom he had hired to work on his house, and he was subsequently buried beneath his floor. Adamson's death and the subsequent trial led to renewed publicity, and was the subject of several true crime television documentaries.
