William Joseph Gabriel Doyle, SJ, MC (3 March 1873 – 16 August 1917) was an Irish Catholic priest who was killed in action while serving as a military chaplain to the Royal Dublin Fusiliers during the First World War.

He was an early member of the Pioneer Total Abstinence Association and had been considered a future leader of the organisation by its founder, Fr James Cullen.

[2] According to Patrick Kenny, anti-Catholicism may have played a role in the British Army's decision not to grant Father Doyle both awards.

[9] General William Hickie, the commander-in-chief of the 16th (Irish) Division, described Father Doyle as "one of the bravest men who fought or served out here.

[2] A stained glass window dedicated to his memory is present in St Finnian's Church, Dromin, County Louth, Ireland.

Despite his troubled relationship with the Roman Catholic Church in Ireland, Irish author and playwright Brendan Behan is known to have always felt a great admiration for Father William Doyle.

Having consulted with the Irish Bishops' Conference and the Dicastery for the Causes of Saints, Deenihan issued an edict on 27 October announcing the opening of a cause.
