Dirk Jan Klaas Huntelaar, known professionally as Klaas-Jan Huntelaar, is a Dutch former professional footballer who played as a striker.

Huntelaar was born in Voor-Drempt, a village in the Achterhoek region of Netherlands, but moved to Hummelo when he was six weeks old. He lived with parents Dirk-Jan and Maud Huntelaar, and his two brothers Niek and Jelle. At the age of five, Huntelaar, along with his two brothers, joined the local football team VV H. en K., where he played for the next six years. He was scouted as a youth talent during this period by Go Ahead Eagles but the distance required to travel to the team's base in Deventer prevented him from joining the club.
