In 2014 Larkin collected his sixth league medal, as Kilkenny secured a narrow one-point 2–25 to 1–27 extra-time victory over Tipperary. He subsequently secured an eighth Leinster medal, as a dominant Kilkenny display gave "the Cats" a 0–14 to 1–9 defeat of Dublin. On 7 September 2014 Kilkenny faced Tipperary in the All-Ireland decider. In what some consider to be the greatest game of all-time, the sides were level when Tipperary were awarded a controversial free. John O'Dwyer had the chance to win the game, however, his late free drifted wide resulting in a draw. The replay on 27 September 2014 was also a close affair. Goals from brothers Richie and John Power inspired Kilkenny to a 2–17 to 2–14 victory. It was Larkin's seventh All-Ireland medal.
