James O'Brien was a nineteenth-century Irish barrister, politician and judge.
He was born in Granard, County Longford, a younger son of James O'Brien and Margaret Long. He went to school in Dublin, and entered the University of Dublin, where he graduated BA in 1829 with a gold medal in science. He entered Gray's Inn in 1831 and was called to the Irish Bar in 1831, becoming Queen's Counsel in 1841.
He entered politics as a Liberal and was elected to the House of Commons as member for Limerick City in 1854; he was re-elected in 1857. He became Third Serjeant in 1848 and Second Serjeant in 1851.
