Leinster and Ulster meet again in the Investec Champions Cup with recent history firmly shaping the narrative. 

Leinster won the most recent meeting between the sides, a 41–17 victory during Round 15 of the 2024–2025 URC season on April 19, 2025. Ulster opened the scoring with an early penalty in that match, but Leinster quickly seized control and led the rest of the way. 

That result continued a trend that has seen Leinster win three straight meetings after Ulster claimed the two prior contests.

Form entering this matchup further underscores Leinster’s momentum. The Dublin-based side has won four of its last five games and carries a four-match winning streak into this fixture at Aviva Stadium. 

Ulster has also been competitive, winning three of its last five matches, but remains tasked with reversing recent results against a Leinster side that has dictated the terms of the rivalry.

With both teams familiar with each other’s structures and tendencies, this Champions Cup clash places emphasis on execution and discipline. Leinster looks to extend its recent dominance, while Ulster seeks to disrupt that pattern and reassert itself on a major European stage.
