The 2026 O'Byrne Cup is a Gaelic football competition for county teams in the province of Leinster.
The draw was announced in November 2025, with the competition starting on 3 January. Features included penalties to decide matches instead of extra time, any number of substitutions permitted, matches being reduced to 60 minutes, and "a Shield competition" intended to guarantee every team is involved in more than one match (except for Louth).
Longford were aiming to complete a three-in-a-row, but were eliminated without playing as their first round game was cancelled due to a frozen pitch. They lost on a coin toss to Westmeath who went on to win the tournament after defeating Louth, Offaly and Kildare.
