He was elected to represent the new seat of North Tipperary, in which Nenagh was situated, in 1885, defeating the Conservative candidate by a margin of 19 to one. He was then returned unopposed in 1886. When the Irish Parliamentary Party split over the leadership of Charles Stewart Parnell in December 1890, O'Brien joined the Anti-Parnellites.
