The 2018–19 Dallas Mavericks season was the 39th season of the franchise in the National Basketball Association (NBA). With an overtime loss to the New Orleans Pelicans on March 18, the Mavericks would once again have a losing season and not make the playoffs for the third consecutive year.
It was Dirk Nowitzki's 21st and final season with the Mavericks, making his season debut on December 13, 2018, against the Phoenix Suns. Not only would he break a record previously set by Kobe Bryant for the most seasons spent playing for a single NBA team, but he also became the fifth player in the NBA history to play in the league for 21 seasons. On March 18, 2019, he became the 6th highest scoring player of all time, surpassing Wilt Chamberlain's 31,419 points. Nowitzki's retirement left former Maverick and fellow 1998 draftee Vince Carter (who played for the Atlanta Hawks) as the last remaining active player to have played in the 1990s.
On January 31, 2019, the Mavericks acquired NBA All-Star Kristaps Porziņģis in exchange for Wesley Matthews and former no. 9 overall pick Dennis Smith Jr.
This was the last time that the Mavericks missed the playoffs until the 2022–23 season.
