John Dunne (21 January 1846 – 25 December 1916) was a Roman Catholic bishop.
He was the first bishop of the Diocese of Wilcannia in New South Wales, Australia.
He studied for the priesthood at Carlow College and was a priest of the Sydney archdiocese.
The request was granted by Archdeacon John Polding and the newly promoted priest worked for 16 years in Goulburn.
Dunne was consecrated the first Bishop of Wilcannia on 14 August 1887 at Goulburn Cathedral, a position he retained until his death.
