William Leggat Ritchie (1884 – 12 February 1966) was a Scottish professional golfer. His most successful year was 1910 when he tied for 16th place in the Open Championship and won the Perrier Water Assistant Professionals' Tournament.
Ritchie was born in 1884 in Aberdeen, Scotland.
Ritchie's best season was 1910 while he was an assistant to James Braid at Walton Heath Golf Club. The opening day of the Open Championship was abandoned because of rain but, when play resumed the following day, Ritchie had rounds of 78 and 74 and was tied for 4th place at the end of the day. Rounds of 82 and 79 on the final day left him tied for 16th place. Later in the year Ritchie won the first Perrier Water Assistant Professionals' Tournament at Bushey Hall Golf Club. The prizes for this tournament were "presented by the proprietors of Perrier Water", the winner receiving 20 guineas (£21) and a gold watch. The event was organised like the News of the World Match Play with regional qualifying over 36 holes and a knock-out stage for the 16 qualifiers. Ritchie won the Southern section qualifying by a clear 7 strokes. Ritchie and Willie Watt, the Scottish qualifier, met in the final. Watt was 1 up after five holes but lost the next four holes. Ritchie also won the 11th and 13th and eventually won 5&4.
