William Reeves (22 June 1875 – 22 March 1944) was an English cricketer, who at the conclusion of his playing career became an umpire, officiating in five Test Matches.

According to Dudley Carew he was "the Sam Weller of umpires, quick of retort, ingenious of smile, unfailing in friendliness".

"[1] Bill Reeves was a medium-pace bowler and a useful hard-hitting batsman who played for Essex from 1897 to 1921, having begun by joining the groundstaff at Leyton Cricket Ground, which was then the county's headquarters.

He scored his other century the following year, 104 against Sussex, when he and Claude Buckenham added 163 for the eighth wicket in only seventy minutes.

From 1910 to 1913 he played in no more than nine matches in any season, but as late as 1920 – when he became 45 years of age – he surprisingly took 62 wickets at 22.59, including the best innings figures of his career, 7/33.

In 1931 he got into trouble when, in a rain-affected match, he and his fellow umpire allowed the two captains to make freak declarations in order to try to produce a definite result.
