Adonal David Foyle (born March 9, 1975 in Canouan, St. Vincent and the Grenadines) is an NBA basketball player. He was selected by the Golden State Warriors with the 8th overall selection of the 1997 NBA Draft and has played with the team during his entire pro career. Foyle played collegiately at Colgate University.
Through his NBA career, Foyle has averaged 4.5 points and 1.9 blocks per game. He has finished amongst the 10 highest players in blocks per game three times during his career.
In his spare time, Foyle writes poetry and is a political activist.
In 2001, he founded Democracy Matters, a non-partisan student organization, as an effort to counteract political apathy on college campuses. The organization's signature issue is campaign finance reform, particularly Clean Elections. Active on over 30 college campuses, Democracy Matters involves hundreds of students and faculty nationwide through teach-ins, letter writing and petition campaigns, educational seminars, and voter registration drives.
In July 2004, during the offseason, the Golden State Warriors re-signed Foyle to a six-year, $42 million contract. The contract was argued by fans to be excessive, locking in a player who averages less than 20 minutes per game and who lacks offensive skills. The last two seasons Foyle has lost his starting role twice. During the 2005-2006 season, Foyle averaged 4.5 points, 5.5 rebounds and 1.6 blocks in 23.7 mintues a game, earning $7,312,500.
Foyle is tied with Tim Duncan of the San Antonio Spurs and Austin Croshere of the Indiana Pacers (9 years) for fourth place among active NBA players who have played their entire career for one team (Kevin Garnett leads all active players, having played 11 years for the Minnesota Timberwolves).
Graduated with a history degree from Colgate University, magna cum laude. Politically motivated, he founded the organization Democracy Matters, which tries to curve the effects of money on politics.  He had an illustrious playing career while at Colgate, setting NCAA single season and career records for blocked shots despite leaving college after his junior season. His final season also saw him lead the nation in points and rebounds per game and matched Colgate up with Tim Duncan and Wake Forest in the first round of the NCAA tournament.
