Scott Allen Skiles (born March 5, 1964 in LaPorte, Indiana) is the head coach of the Milwaukee Bucks and former American professional basketball player. He also is the former head coach of the NBA's Chicago Bulls and Phoenix Suns. Skiles holds the NBA record for assists in one game, with 30. In 1990-91 he won the NBA Most Improved Player Award. He was released as head coach of the Chicago Bulls on December 24, 2007. He will live in Milwaukee during the season.

In 1982, Skiles led Plymouth High School to the Indiana State Championship. Plymouth, with no starter taller than 6'2" and no reserve taller than 6'6", was considered to be the weakest of the final four teams in the tournament that year even though they were ranked #4 in the state with a record of 26-1 entering the state finals. Amazingly, they won the state title with a 75-74 double overtime victory over favored Gary Roosevelt. In that game, Skiles scored 39 points (to follow-up his 30 point performance against Indianapolis Cathedral that morning) to lead the Pilgrims past the Roosevelt Panthers. His long 22-foot (6.7 m) field goal, that was well beyond where the current three-point line is (no three-point shot existed in 1982) as time expired sent the game into overtime. Many consider the game one of the most memorable finals from the era of classless basketball in Indiana, when all high schools in the state competed for a single championship regardless of enrollment. Indiana adopted a multiclass tournament in 1998, and prior to that it was much more difficult for smaller schools to compete and win the title. Plymouth was the smallest school to win the championship since Milan in 1954. (Milan's story has been immortalized in the movie Hoosiers.) Plymouth High School enrollment at that time was about 900 students attending grades 9 through 12. Skiles scored 25 of his 39 points in the championship game after the third quarter of play. During the 1982 season, Skiles led the state in scoring, averaging 30.2 points per game. He set several records during high school, including most points in a home game (53) and most points in an away game (56). He left Plymouth as the schools all-time career scoring leader (1,788 points). A record that would stand until 2005 (Kyle Benge-1,979 points). Skiles had his number 22 jersey retired at Plymouth High School in 1992.

Skiles attended Michigan State University, where in his senior season he was a First Team All-America selection as well as the Big Ten Conference MVP and scoring champion. He left MSU as its all-time career scoring leader (2,145 points) and still holds the Spartans' record for most points scored in a season (850). While in East Lansing, he was arrested and charged with felony possession of cocaine and misdemeanor possession of marijuana. The cocaine charge was dropped when Skiles pleaded guilty to the marijuana possession. He was arrested and charged with drunken driving a year later and served 15 days in jail. During his senior season, Skiles committed a parole violation on an earlier marijuana conviction, and served a brief jail sentence.
