Hollywood actor Jeff Goldblum has won a restraining order against a woman he claims has been stalking him for six years.

Linda Ransom, 44, has been ordered to maintain a distance of at least 100 metres from the Jurassic Park star's home, workplace and vehicle.

The actor told the Los Angeles Superior Court that he had suffered an "escalating pattern of harassing, threatening, and stalking behaviour", including threatening letters, since 2001.
