Rehn, with Finnish parents, received a call-up for the Sweden national under-18 football team but was ineligible to play until 1984 when he acquired Swedish citizenship. In total, he made eight U18 appearances (one goal) and 17 U21 appearances (three goals).
Rehn made his international debut in a 1988 4–1 friendly win against East Germany national football team, a match in which he also scored his first international goal in the 58th minute. He played two matches in the 1988 Summer Olympics for Sweden. He was part of the UEFA Euro 1992 squad, but did not play.
