A 1-15 to 2-11 win over Crossabeg-Ballymurn brought a fourth intermediate county title, promotion to senior, and a run into the All-Ireland Intermediate Club Championship.
On 17 October 2015 Naomh Éanna beat Crossabeg-Ballymurn 1-15 to 2-11 in the Wexford Intermediate Hurling Championship final. Conor McDonald scored 1-05 from full-forward. It was the club's fourth intermediate county title, following 1974, 1990 and 2001.
The victory did two things at once. It won a county championship, and it earned promotion to the Wexford senior grade — the platform on which the 2018 and 2023 senior titles were later built.
It also sent the club on the road. Naomh Éanna went into the 2015–16 All-Ireland Intermediate Club Hurling Championship, where their campaign ended against Kiltale of Meath. For a Gorey club that had spent decades outside the county's top tier, an All-Ireland series was uncharted territory.
Looking back, 2015 is the hinge year in the club's story: the last season Naomh Éanna were an intermediate club, and the first season they behaved like a senior one.
