George A. Birmingham was the pen name of James Owen Hannay (16 July 1865 – 2 February 1950), Irish clergyman and prolific novelist.

He was active in the Gaelic League, but strained his relations with Irish nationalists by supporting Robert Lindsay Crawford in his opposition to clerical control of education.

Hannay became rector of Kildare parish from 1918 to 1920, and after serving as chaplain to the Viceroy of Ireland, he joined the British ambassadorial team in Budapest in 1922. He returned to officiate at Mells, Somerset from 1924 to 1934, after which he was appointed vicar of Holy Trinity Church in the London suburb of Kensington where he served from 1934 to his death in 1950.
