The 2009–10 New Jersey Nets season was the 43rd season of the franchise, 34th in the National Basketball Association. This was the team's final season at the Izod Center. With a loss to the Dallas Mavericks on, the Nets became the first team in NBA history to start the season 0–18. The Nets got their first win of the season at home against the Charlotte Bobcats on. With a loss to the Houston Rockets on, the Nets became the sixth team in NBA history to lose 28 of its first 30 games, tying the worst 30-game record in NBA history. With a loss to the Utah Jazz on, the Nets became the third team in NBA history to lose 40 of its first 43 games, tying the worst three-win record in NBA history. On February 6, the Nets lost to the Detroit Pistons, falling to 4–46 and tying the record for worst 50-game record in the history of the three major sports that play seasons that long.
November 29 – Lawrence Frank was relieved of his duties as head coach after the team began the season with 16 consecutive losses, one shy of the NBA record. This streak was ongoing at the time of his dismissal. Tom Barrise, who previously served as assistant coach under Frank, became his replacement as interim head coach for the Nets' game that night against the Los Angeles Lakers, which the Nets lost 106–87 for their record-tying 17th consecutive loss. After a two-game stint by Barrise, general managerKiki Vandeweghe was named the head coach for the remainder of the season, and Del Harris was given a position as assistant coach.

Injuries and surgeries
missed 10 games at the beginning of November due to a groin strain before returning on November 21 against the New York Knicks. In addition, at one point the entire starting lineup, with the exception of center Brook Lopez, was injured. For a considerable portion of the season the Nets were forced to play extremely short-handed, and multiple times were able to dress only the league-minimum seven players. This was a major contributor to the poor start the Nets had for the season, in addition to well-respected Head Coach Lawrence Frank being fired and replaced by Nets GM/rookie head coach Kiki Vandeweghe.
