Shelden DeMar Williams (born October 21, 1983 in Oklahoma City, Oklahoma) is an American professional basketball player for the NBA's Sacramento Kings. On February 16, 2008, Williams was involved in a multi-player trade to the Sacramento Kings for Mike Bibby (the trade is pending league approval and physical examinations). Williams, a former Duke University star, was selected by the Hawks with the fifth pick in the 2006 NBA Draft. His jersey number, 23, was retired by Duke University on January 28 2007.

His size (6'9", 250 lbs.), aggressive style of play, and shot-blocking ability make it seem as though he "owns the paint," thereby earning him the nickname "The Landlord." Williams earned the 2005 and 2006 NABC Defensive Player of the Year Awards while at Duke, becoming only the fifth player in history to earn the award two consecutive years. He holds Duke's career blocks record, single-season blocks record, and career rebounding record, while he is 17th in career blocks on the NCAA charts. He is the third player in ACC history to have 1,500 points, 1,000 rebounds and 350 blocks (joining Tim Duncan and Ralph Sampson). His 1,217 rebounds and 1,859 career points rank him seventh in ACC history and sixteenth in Duke history, respectively. Williams became only the third Duke basketball player to record a triple-double when Duke defeated Maryland on January 11, 2006, recording 19 points, 11 rebounds and 10 blocks. During high school, Williams was a member of the National Honor Society and the Fellowship of Christian Athletes. He notes his favorite athletes as Shaquille O'Neal and Kevin Garnett. He is currently engaged to University of Tennessee Lady Vols basketball star, Candace Parker. On December 15, 2007, Williams was carjacked at gunpoint before a game against the Charlotte Bobcats. Two suspects were arrested later that day at Arbor Place Mall in Douglas County, Georgia. According to an officer at the Douglasville Police Department, the suspects were in Williams' car and were attempting a robbery.
