Charles Keith Quentin Jackman (4 February 1906 – 23 February 1988) was a cricketer who played first-class cricket for Canterbury and Auckland between 1935 and 1942 and represented New Zealand in 1935-36.
A wicket-keeper, Jackman made his first-class debut for South Island against North Island in 1934-35, making one catch and four stumpings.
The next season, playing for Canterbury against Wellington, he set a New Zealand record when he made seven stumpings in the match, six of them off the leg-spin of Bill Merritt.
Later in 1935-36 he was selected for two of the four matches New Zealand played against MCC.
