Keith Van Horn (born October 23, 1975 in Fullerton, California) is an American basketball player currently playing forward for the Dallas Mavericks. Van Horn played for the University of Utah and was drafted in 1997 by the Philadelphia 76ers with the number two pick overall, behind number one pick Tim Duncan.
Van Horn has played for the New Jersey Nets, the Philadelphia 76ers, the New York Knicks, the Milwaukee Bucks, and the Dallas Mavericks. Standing at six feet, ten inches (2.08 m) tall, the lanky Van Horn is easily recognized for his wearing knee-high white or black socks. Keith is widely regarded as a post player who can kick it out to the baseline and fire a long range shot. On the other hand, he has a reputation for being a soft defender and being injury-prone.
Among Van Horn's accomplishments is being the first player in the Western Athletic Conference to be named Player of the Year three times (1995, '96, '97), being the second player in WAC history to make first-team all-WAC four years, and being the leading career scorer in Utah and WAC history with 2,542 points.
He has been a literacy spokesman for the Nets and the NBA.
