Tankerville Chamberlayne (9 August 1843 – 17 May 1924) was a landowner in Hampshire and a member of parliament, serving the Southampton constituency three times, as an Independent and Conservative. He was deprived of his seat after the 1895 general election because of the indiscretion of one of his campaign workers and his having headed a procession which raised suspicion of having supplied beer to supporters. He subsequently raised the question of false electioneering statements in Parliament.
