Jack Hoyne (born 28 February 1880) was an Irish hurler who played as a full-back for the Kilkenny senior team.
Tullaroan retained the title the following year, with Hoyne claiming a sixth championship medal following a 4–3 to 2–5 defeat of Mooncoin.
Hoyne made his debut with the Kilkenny senior team during the 1902 championship, however, their campaign ended in a single-point defeat by Dublin in the Leinster decider.
The game against Dublin ended in a 1–5 apiece draw, however, Kilkenny were subsequently awarded the title by the Leinster Council.
Hoyne's side later trounced Antrim before lining out against Cork in the All-Ireland home final which wasn't played until 11 July 1905.
Hoyne added a second Leinster medal to his collection in 1904 as Kilkenny recorded a 2–8 to 2–6 defeat of Dublin in the provincial decider.
The game, however, had to be replayed as Cork goalkeeper Daniel McCarthy was a British army reservist and Kilkenny’s Matt Gargan had earlier played with Waterford in the Munster championship.
