Dorothy Ruth Hoogstraten (February 28, 1960 – August 14, 1980), who took the stage name Dorothy Stratten, was a Canadian Playboy Playmate, model, and actress. Stratten was the Playboy Playmate of the Month for August 1979 and Playmate of the Year in 1980. Stratten appeared in three comedy films and in at least two episodes of shows broadcast on US network television. She was murdered at the age of 20 by her estranged husband/manager Paul Snider, who committed suicide on the same day. Her death inspired two motion pictures, the 1981 TV movie Death of a Centerfold and the 1983 theatrical release Star 80, as well as the book The Killing of the Unicorn and the song "Californication" by the Red Hot Chili Peppers.
Stratten was born in Grace Maternity Hospital in Vancouver, British Columbia, to Simon and Nelly Hoogstraten, who had immigrated from the Netherlands. In 1961, her brother John Arthur was born and, in May 1968, her sister Louise Stratten.
