The 2024–25 season was Leinster Rugby's fourth season in the United Rugby Championship (URC), their 31st season of professional rugby and their 137th season of representative rugby since their foundation. Along with competing in the URC and its Irish Shield competition, the club also participated in the 2024-25 European Rugby Champions Cup.

In the latter competition, seeking a record fourth successive final, Leinster suffered a shock home defeat in the semi-final to Northampton Saints, ending their run of final appearances. In the URC, however, they reached their first final in the new format, against Bulls of Pretoria. They reached the play-offs as top seeds from the regular season, and retained their Irish Shield title for the fourth time. In the final, they overcame second seed Bulls 32-7 to win the championship for a record nineth time.

In the women's game, Leinster retained their Interprovincial Series title despite a loss to Munster Women, and supplied the bulk of the players to the Wolfhounds franchise that retained their Celtic Challenge title.
