Thomas Mayne (1832–1915) was an Irish Parliamentary Party politician. He was elected as Member of Parliament (MP) for Tipperary at a by-election in 1883,[1] and held the seat until the constituency was divided at the 1885 general election. He was then elected for the new Mid division of Tipperary,[2] and held that seat until he resigned in 1890 by becoming Steward of the Manor of Northstead.[3]
