William Roy Genders (21 January 1913 – 28 September 1985) was an English first-class cricketer who played for Derbyshire in 1946, for Worcestershire from 1947 to 1948 and for Somerset in 1949. Genders was born in Dore, then in Derbyshire. He played several games for Derbyshire in 1945 before first-class cricket was resumed after the war. He remained with Derbyshire in the 1946 season, appearing thrice with little success. During the next 1947 and 1948 seasons he played five times for Worcestershire, and it was here that he recorded his best performances. He made 55 not out against his old club Derbyshire, and took all his three wickets for the county in a single match against Gloucestershire; the most notable of his victims was probably "one-Test wonder" George Emmett.
