Christopher Anton Knight (born November 7, 1957) is an American actor famous for his role on the TV show The Brady Bunch, on which he played the role of Peter Brady from 1969 to 1974. His final acting job as Leigh Hobson on Another World in the early 1980s, he has made a career primarily out of guest appearances on other television shows. On top of this, Christopher also helped to create The Brady Bunch Movie (1994) and also made a Brady Bunch computer game. He is well-respected in the IT industry.

Knight appeared on VH1's 4th season of The Surreal Life with Da Brat, Chyna, Jane Wiedlin, Adrianne Curry, Verne Troyer, and Marcus Schenkenberg. The show garnered Knight more attention than he had received in quite some time, due to viewer surprise at his hunky body and his budding romance with the volatile and younger Curry. As of May 2005 the two are living together, as documented on the VH1 series My Fair Brady, which premiered on September 11, 2005.

He was also recently featured in a music video for the group Click Five, in which he played a high school teacher.
