William Lacey (24 September 1889, Enniscorthy, County Wexford, Ireland – 30 May 1969) was an Irish footballer who played for, among others, Shelbourne, Liverpool, Everton and Linfield.
Lacey was a dual international and also played for both Ireland teams – the IFA XI and the FAI XI.
An extremely versatile and talented player, Lacey played in all eleven positions during his career.
He was a prominent member of the Ireland team that won the 1914 British Home Championship and was also a member of the Liverpool team that won two successive English First Division titles in 1922 and 1923.
He was also the first player to be capped at full international level while playing for both Everton and Liverpool.
In 1927 at the age of 37, he became the oldest player to make his debut for an FAI XI, and in 1930 at the age of 41 he became the FAI XI's oldest ever player.
After retiring as a player, Lacey became a coach, most notably with the FAI XI and Bohemians.
