William Fielding (17 June 1915 – May 2006) was an English footballer who played as a goalkeeper for Cardiff City, Bolton Wanderers and Manchester United in the 1930s and 1940s.
Born in Broadhurst, Congleton, Cheshire, Fielding began his football career playing for the Broadbottom YMCA's team, before joining Hurst.
In May 1936, at the age of 20, Fielding joined Cardiff City, where he played until the outbreak of the Second World War in 1939, making a total of 50 appearances in that time.
In January 1947, Fielding signed for Manchester United as cover for the injured Jack Crompton in a deal which saw Billy Wrigglesworth move to Bolton.
He made his debut on 25 January 1947, playing in the club's FA Cup Fourth Round defeat to Nottingham Forest.
