Robert Bowlby Blake (born December 10, 1969) is a Canadian professional ice hockey defenceman currently playing for the San Jose Sharks of the National Hockey League (NHL).

Blake was drafted 70th overall in the 1988 NHL Entry Draft by the Los Angeles Kings, with whom he played for twelve seasons. While there, he reached the Stanley Cup final in 1993, losing to the Montreal Canadiens, and eventually became the Kings' captain after Wayne Gretzky was traded to St. Louis in 1996.

In the 2000–01 season, Blake, who the Kings believed would test free agency in the coming off-season, was traded by the Kings. Blake, along with Steven Reinprecht, went to the Colorado Avalanche for Adam Deadmarsh, Aaron Miller, Jared Aulin and a 1st round pick (David Steckel) on February 21, 2001. Blake helped the Avalanche in winning the Stanley Cup that same year.
