Christopher Anton Knight (born November 7, 1957 in New York, New York) is an American actor best known for playing Peter Brady on the 1970s series, The Brady Bunch. He has since gone on to become a successful businessman and has enjoyed a semi-resurgence in the public eye with recent TV appearances. He currently hosts the syndicated game show Trivial Pursuit: America Plays. His father, Edward Knight, is also an actor.

Since the end of his Brady Bunch appearances, Knight's acting career consisted mostly of making guest appearances on other television shows. He also helped create a Brady Bunch computer game and is well-respected in the IT industry, according to a TV Land documentary about the Brady Bunch.

An interest in science and machines led Knight to a career in the computer industry in 1988. His celebrity status helped him to hone skills in sales and marketing. Entering the industry as an account sales manager at Martec, Inc., he logged the company's first US$1 million sales order within his first eighteen months, quickly becoming Martec's top performer, and employee of the year.
