Rezaul Karim Rehan (Bengali: রেজাউল করিম রেহান; born 6 September 1968) is a retired Bangladeshi footballer who played as a defender for the Bangladesh national team from 1987 to 1993.

In the same year, he played unofficial matches for the national team during the Quaid-e-Azam International Cup held in Pakistan.

He made his official senior international debut during a 0–1 defeat to Thailand in the 1990 FIFA World Cup qualifiers on 19 February 1989.

[7][8] During the 1989 South Asian Games, when Bangladesh took on India in the second group-stage match, they managed to take the lead through Nurul Haque Manik, however after a challenge from Rehan in the penalty box, Bangladesh conceded a late penalty which led to captain Elias Hossain pushing the referee in anger, earning him a ban from international football.

In 1993, during the 1994 FIFA World Cup qualifiers return game against Japan, Rehan was sent off for the second time in his international career as Bangladesh suffered a 4–1 defeat.
