James Francis "Jim" Lynam (born September 15, 1941) is an American former college and professional basketball coach. He coached at the college level for Fairfield University from 1968 to 1970, American University from 1973 to 1978, and St. Joseph's University from 1978 to 1981. In the National Basketball Association (NBA), Lynam coached the San Diego Clippers/Los Angeles Clippers from 1983 to 1985, the Philadelphia 76ers from 1987 to 1992, and the Washington Bullets from 1995 to 97. Lynam compiled a 158–118 record at the college level, and 328–392 in the NBA. He was also Philadelphia's general manager from 1992 to 1994.
Lynam coached St. Joseph's to an upset victory over #1 ranked DePaul by a score of 49–48 in the second round of the 1981 NCAA Men's Division I Basketball Tournament. In their opening game his 9th seeded Hawks topped #8th seed Creighton 59-57. They would win their third tournament game over #5 seed Boston College 42-41 before falling to the National Champion, Indiana at a game on their home floor in Bloomington. Ironically had they won that game Lynam's Hawks would have been in the Final Four at The Spectrum in Philadelphia.
Lynam has also served as an assistant coach for several teams, most notably the Sixers and the Portland Trail Blazers, the latter for head coach Maurice Cheeks. When Cheeks was hired as Philadelphia's coach for the 2005–06 season, Lynam was named an assistant. During the preseason, however, he was forced to leave the team due to an undisclosed medical condition. In January, 2006, Lynam retired from coaching. However, on September 29, 2006 it was announced that Lynam, along with NBA hall of famer Moses Malone would be rejoining the 76ers as an assistant coach. In July 2010, The Oregonian reported that Lynam was among candidates for an assistant coaching job in Portland.
