The 2018–19 Duleep Trophy was the 57th season of the Duleep Trophy, a first-class cricket tournament in India, which took place in August and September 2018. India Red were the defending champions. All of the matches took place at the NPR College Ground in Dindigul. The BCCI's technical committee structured the tournament to have four teams from four Ranji Trophy Groups, similar to the 2002–03 Duleep Trophy, but on the day of team selections, the format of the previous season was retained. India Blue won the tournament, beating India Red by an innings and 187 runs in the final.
