Newton Wallop, 6th Earl of Portsmouth JP, DL (19 January 1856 - 4 December 1917), styled Viscount Lymington until 1891, was a British Liberal politician but then joined the Liberal Unionist Party in 1886. He later switched back to the Liberal Party to serve as Under-Secretary of State for War under Sir Henry Campbell-Bannerman from 1905 to 1908.

Lymington was born in Whitchurch, Hampshire, the eldest son of Isaac Wallop, 5th Earl of Portsmouth, and his wife Lady Eveline Alicia Juliana Herbert, daughter of Henry Herbert, 3rd Earl of Carnarvon. He was educated at Balliol College, Oxford.

Lymington was elected Member of Parliament (MP) for Barnstaple at a by-election in February 1880, a seat he held until 1885 when representation was reduced to one member under the Redistribution of Seats Act 1885. At the 1885 general election, he was elected MP for South Molton and held the seat until 1891. In the latter year he succeeded his father in the earldom and took his seat in the House of Lords. From 1905 to 1908 Lord Portsmouth served as Under-Secretary of State for War in the Liberal administration of Sir Henry Campbell-Bannerman.
