William Nicholson (2 September 1825 – 25 July 1909) was an English distiller and Liberal Party politician who sat in the House of Commons in two periods between 1866 and 1885, and later joined the Conservative Party. He was also an English amateur cricketer who played first-class cricket from 1845 to 1869.
Nicholson was born at Upper Holloway, London, the son of John Nicholson of Upper Clapton, Middlesex and his wife Ellen Payne daughter of Richard Payne. He was educated at Harrow School and Trinity College, Cambridge. He was a member of the family which owned the J&W Nicholson & Co gin distillery based at Three Mills. He was mainly associated with Marylebone Cricket Club (MCC), of which he was a prominent member; and with Middlesex (pre-county club) and Middlesex County Cricket Club (founded during his career in 1863). He was a right-handed batsman and a wicketkeeper who made 148 known appearances in first-class matches, including a number of appearances for the Gentlemen between 1846 and 1858.
Nicholson became a director and then chairman of the distillery and was a benefactor of cricket. In 1863 he acquired Basing Park, Alton, Hampshire. In 1864, when MCC finally purchased the freehold of Lord's Ground, they paid £18,333 6s 8d using money advanced by Nicholson. In 1889, when the foundation stone was laid for the new Lord's Pavilion, it was paid for by a £21,000 loan from Nicholson. He was a J.P. and Deputy Lieutenant for Hampshire
In July 1866 Nicholson was elected unopposed as the Member of Parliament (MP) for the borough of Petersfield in Hampshire, at a by-election caused by the elevation to the peerage of the Conservative MP Sir William Jolliffe. He was re-elected in 1868, but defeated at the 1874 general election. In 1878, he was High Sheriff of Hampshire. He was re-elected for Petersfield in the 1880 general election and held the seat until the parliamentary borough of Petersfield was disenfranchised under the Redistribution of Seats Act 1885. The name was transferred to a new county division of Hampshire. With a wider geographical area, and a franchise expanded under the Representation of the People Act 1884, the new seat had an electorate more than ten times larger, expanded from 801 in 1880 to 8,202 in 1885. In April 1885 Nicholson announced his resignation from the Liberal Party, stating that he would contest the next election as a Liberal-Conservative. He was adopted by the local Conservative association as their candidate, but at the general election in December that year he lost the seat by a narrow margin to the Liberal candidate Viscount Wolmer, and was defeated again at the 1886 election.
