The 2024 season was D.C. United's 29th in existence and its 29th consecutive season in the top division of American soccer, Major League Soccer. In addition to MLS, D.C. United participated in the 2024 Leagues Cup.
United finished the season 20th in the league and 10th in Eastern Conference, an improvement from 2023 where they finished 12th in the Eastern Conference, and 23rd overall. However, on the final day of the season, the club lost at home causing them to miss the playoffs for the fifth-consecutive season.
Christian Benteke finished the season with 23 goals in league play and 25 goals in all competitions, allowing him to win the MLS Golden Boot. Benteke became the first United player since Dwayne De Rosario in 2011 to win the Golden Boot.
The 2023 season was the first, and only, full season with Wayne Rooney in charge of managerial duties for United. Under Rooney's leadership the club improved in form and finishing with 40 points on the season, up from 27 the previous season. However, the improvement was not enough to qualify for the 2023 MLS Cup Playoffs, resulting in Rooney's dismissal. Despite calls for his resignation by fans, Sporting Director Dave Kasper was not fired during the offseason.
Outside of league play, United reached the fourth round of the 2023 U.S. Open Cup and the round of 32 in the 2023 Leagues Cup. Christian Benteke lead United with 14 goals across all competitions.
The top eight teams that did not already qualify for the 2024 CONCACAF Champions Cup, excluding the defending Open Cup champion, qualified for the 2024 U.S. Open Cup. D.C. United did not finish in one of the positions to qualify for the tournament.
