Petra  Verkaik (born November 4, 1966, Los Angeles, California) is an adult model known primarily for her many appearances in Playboy publications. As of 2002, Verkaik held the record for most appearances in Playboy magazines and Playboy Special Editions.

The prodigiously endowed Verkaik was Playmate of the Month for December 1989 after first appearing in the Great Playmate Hunt Special Edition in February 1989. As she describes it, "Playboy just bounced off my chest and fell into my lap." She owes her exotic looks to her father is from Holland and her mother, who is from Sumatra, Indonesia.

Some detractors have suggested that Verkaik had a nose job in the early 1990s, but Petra has stated that she has never had cosmetic surgery of any kind, including breast implants.
