The 1999–2000 NBA season was the Hawks' 51st season in the National Basketball Association, and 32nd season in Atlanta. The Hawks played their first season at the Philips Arena, which was built over the site of The Omni. The Hawks received the tenth pick in the 1999 NBA draft from the Golden State Warriors, and selected Jason Terry from the University of Arizona. In the off-season, the team acquired Isaiah Rider and Jim Jackson from the Portland Trail Blazers, acquired Bimbo Coles from the Golden State Warriors, and acquired Lorenzen Wright from the Los Angeles Clippers.
