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.
He played several games for Derbyshire in 1945 before first-class cricket was resumed after the war.
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.
In this match, all eleven Somerset players (and Extras) reached double figures, but none went on to score a half-century.
Genders was a right-handed batsman and played 19 innings in ten first-class matches with an average of 16.33 and a top score of 55 not out.
