William Lewis Boyle (27 May 1859 – 2 October 1918) was Liberal Unionist MP for Mid Norfolk.
He was the grandson of Vice-Admiral Sir Courtenay Boyle.
Boyle joined the Conservative Party when it merged with the Liberal Unionists in 1912.
He died in office; the resulting by-election had only one candidate because of the wartime truce.
