Allan Kierstein Jepsen (born 4 July 1977 in Kolding) is a Danish former professional football player and current U17 manager at FC Midtjylland.

The young defender, however, never broke into the starting eleven on the highest level, and before the 2000–01 season he returned to the Danish Superliga outfit AaB, poised to replace club legend Jens Jessen.

After almost 200 matches for AaB, Jepsen finally achieved a full cap for the Danish national team on 2 June 2005, coming on for Niclas Jensen at the 71st minute in the 1–0 win over Finland.

On 13 March 2006, Jepsen used a clause in his contract as he signed for the Norwegian club Vålerenga for a €335,000 transfer fee.

He revealed that the chance of playing in the UEFA Champions League was one of the chief reasons in choosing his new club.
