John William Keene (25 April 1873 – 3 January 1931) was an English first-class cricketer who played for Surrey, Worcestershire and Scotland around the turn of the 20th century.
Having already made a number of appearances for Surrey Second XI, Keene's first-class debut for the county came against Warwickshire at Edgbaston in June 1897: he took 3–61 in the first innings, his maiden victim being Walter Quaife.
Keene reappeared in county cricket in 1903, when he played 13 times for Worcestershire, and collected a season's best aggregate of 36 wickets at an average of 17.88.
Earlier that summer he had bowled unchanged throughout Warwickshire's first innings with Ted Arnold: both men recorded figures of 5/44.
After that season, he was to play only one more first-class game, making a single appearance for Scotland, against the South Africans at Edinburgh in July 1907; his 17 wicketless overs went for 94.
