David Byas (born 26 August 1963)) is an English first-class cricketer, who played for Yorkshire and latterly Lancashire, in a 17 year first-class career. Byas grew up on a farm in Yorkshire, having attended school at Scarborough College. He was a left-handed batsman who scored a century, on the day his son was born, and very occasionally bowled right-arm medium pace. He was appointed Yorkshire's captain at the start of the 1996 season, following the resignation of Martyn Moxon. In 2001, he led the county to their first County Championship title win for 33 years, sealing the championship with a catch taken at North Marine Road.
