In 2007 Ó Sé had a fine National League campaign which carried on into the Munster Championship. That year Kerry faced Cork in the provincial decider once again. A close game developed; however, at the full-time whistle Kerry were the champions by 1–15 to 1–13. It was Ó Sé's ninth Munster winners' medal. Kerry then had the narrowest of victories in their All-Ireland quarter-final against Monaghan, setting up a glamour All-Ireland semi-final tie with Dublin. Ó Sé spent much of the game on the bench after picking up a hip injury, however, he was introduced as a substitute to help Kerry see off a Dublin comeback and win by two points. The subsequent All-Ireland final was an historic occasion as Kerry faced Cork in the very first all-Munster championship decider. While the first half was played on an even keel, 'the Kingdom' ran riot in the second half and a rout ensued. Cork goalkeeper Alan Quirke came in for much criticism after conceding some easy goals. At the full-time whistle Cork were trounced by 3–13 to 1–9. It was a fifth All-Ireland medal for Ó Sé, his fourth on the field of play. A third All Star award quickly followed.
