William Henry (Bill) Brown (18 June 1899 – 16 October 1967) was a New Zealand politician of the National Party.
Brown was born in Napier in 1899, the son of Henry Stafford Brown and his wife Ellen Susannah Brown (née Day).
Brown first contested the Palmerston North electorate at the 1957 election against the incumbent, Philip Skoglund of the Labour Party. That year, Skoglund was confirmed by the voters. However, in the 1960 election, Brown beat Skoglund by the narrow majority of 123 votes. At the 1963 election, Brown had a 772-vote majority to Skoglund. The 1966 election was contested by Brown against Labour's Joe Walding, with Brown holding a 259-vote majority. Brown died in office in 1967. He was succeeded by Walding through a by-election later in 1967.
Brown died on 16 October 1967 in Kaiapoi while speaking at a function after the opening a section of the Christchurch Northern Motorway.
