The 2018 O'Byrne Cup was played by county teams of Leinster GAA. It began in December 2017 and ended in May 2018.[1][2][3]
On 14 January 2018, the result of the Meath versus Longford semi-final was determined by a free-taking competition, as the score was level at the end of both normal time and extra time. Each side took five free kicks from the forty five metre line and Meath won 2-1. This was the first inter-county Gaelic match to be decided in this way (previously the match would have been replayed).
The final was delayed on multiple occasions due to bad weather; it was finally played in May, with Meath the winners.[4]
