Bob Wilkens, played by Mark Metcalf, was a recurring character seen in the third season of Melrose Place, the second series of the Beverly Hills, 90210 continuity.

Bob was an internal affairs detective within the Los Angeles Police Department. He came to interview Jo Reynolds following an incident with Detective John Rawlings in which he beat a suspect into a coma.

Matt Fielding later brought Wilkens photos that Jo took of the incident, which implicated Rawlings in the wrongful death of a suspect. Wilkens promised to keep Jo's involvement to a minimum, but Rawlings spied on their meeting.
