John Dicker (30 March 1815 – 30 March 1895) was an English cricketer who played for Kent sides.
Dicker was born in Cudham in Kent in 1815, the son of William and Sophia Dicker. His father was a miller at Hever. Dicker himself worked as a carpenter, wood turner and as a cricket bat maker, initially at Hever and then at Edenbridge.
Dicker played for a variety of local cricket teams, including for Westerham and Penshurst. He was one of the first players to employ roundarm bowling regularly. He played in three first-class matches, two for Kent sides in 1840 and one in 1844 in a Married v Single game. This was a benefit match for the players involved in it.
Dicker married Susannah Dicker from Sussex in 1842. He died at Westerham in 1895 on his eightieth birthday.
