Laurence O'Donnell DD (1777 – 29 June 1855) was a Roman Catholic Bishop of Galway, starting in 1844; he was appointed September 26, and consecrated October 28.
Born in Oldchapel, Oughterard, Co. Galway, Laurence entered St. Patrick's College, Maynooth in 1800 to train for the priesthood.
He tutored his Nephew Dominic Bodkin, the son of his sister Eleanor, who went on to be a Physician in America.
His residence, Fort Lorenzo, Taylors Hill, Galway, was purchased by Mrs Kirwan his sister for him.
[3] Bishop O'Donnell was seen as being ineffectual by Cardinal Cullen, in not counteracting the proselytizing by protestants in the west of Ireland during the famine, also in the lack of Catholic influence (and inability to award degrees in theology) in the establishment of the Queen's Colleges.
