Patrick Livingston Murphy Williams (May 3, 1940 – July 17, 2024) was an American sports executive, who served as senior vice president of the Orlando Magic. Williams began his career as a minor league baseball player, and later joined the front office of his team. In the late 1960s he moved into basketball, with his biggest achievements being the 1983 title of the Philadelphia 76ers and being a partner in the creation of the Orlando Magic.

Williams was born in 1940 in Philadelphia, the second oldest of four children and the only son. He was raised in Wilmington, Delaware, attending Tower Hill School where his father coached and taught. He became a friend of Ruly Carpenter, son of Philadelphia Phillies owner Bob "R.R.M." Carpenter, who would bring Williams to the Phillies’ dugout and clubhouse, as well as to the team's spring training in Clearwater, Florida.

His interest in baseball would earn Williams a scholarship to Wake Forest University. There Williams earned a bachelor's degree in physical education in 1962 while being a catcher on the Demon Deacons baseball team. Williams later earned a master's of science degree in physical education from Indiana University in 1964, and served for seven years in the United States Army, He later got a doctorate in Humane Letters from Flagler College.

Former Chicago White Sox owner Bill Veeck is credited by Williams as his mentor, with a visit to Veeck in 1962 starting their friendship and giving Williams principles followed in his career, such as "Don’t announce promotions in advance, be out on the speaking circuit, stand at the gates when fans leave, open your own mail and don’t screen your calls".

Williams' baseball career began when the Carpenters signed him in 1962 to the Miami Marlins, their minor league team in the Florida State League. He was a catcher for two years then retired and moved in to a front office role. Marlins general manager Bill Durney still saw in Williams an eager and natural leader with a marketing degree, and invited him to be the team's business manager. One year later, the Phillies appointed him to be the general manager of the Spartanburg Phillies. As the Phillies became a powerhouse of the Western Carolinas League, Williams was later elevated to the position of president of the organization in 1967, and was chosen the Minor League Executive of the Year by The Sporting News. Afterwards he spent three years in the Minnesota Twins organization.

Even after moving to basketball, Williams was still active in baseball—every winter, he played in Major League Fantasy Camps. He was also president of Orlando's Double-A Southern League team from 1990 to 1993.^{[citation needed]}

Williams moved into basketball in 1968, becoming the Philadelphia 76ers business manager. With promotions that included elaborate halftime shows and a successful 55-27 performance, the 76ers were third in attendance of the 1968–69 NBA season. Afterwards the faltering Chicago Bulls hired Williams to become their general manager. Williams immediately revamped the team's roster, trading with the Sixers for Chet Walker, and invested on the promotion, including the creation of mascot Benny the Bull. He succeeded Richie Guerin as general manager of the Atlanta Hawks on August 6, 1973, in that the Hawks had felt the need for a GM who specialized in promotion. He spent just one year in Atlanta, where his most notable action was trading star Pete Maravich for two players and five draft picks.

As the Sixers had become one of the worst teams in the NBA, owner Irv Kosloff invited Williams to return in 1974. Williams then remained in Philadelphia for 12 years as their general manager, helping to build the team that won the 1983 NBA Finals, by trading for Julius Erving and Moses Malone, and drafting Maurice Cheeks and Andrew Toney. Frustrated at his failure to build a 76ers dynasty despite bringing new talent such as Charles Barkley, Williams left the organization in 1986.
