John Dicker (30 March 1815 – 30 March 1895) was an English cricketer who played for Kent. He was born in Cudham and died in Westerham. Dicker made two first-class appearances for Kent in 1840, scoring one run in the first match, batting first as a tailender, and in the middle order, while in his second match for the team, he was promoted to second in the batting order, where he scored two runs in what is, to this day, one of the lowest totals in first-class cricket for Kent.
