Wilsecker is a municipality in the district of Bitburg-Prüm, in Rhineland-Palatinate, western Germany.

Wilsecker is a small town of approximately 200 inhabitants, close to the border of Luxembourg. Wilsecker is host to a respectively high percentage of American citizens as it is a very affordable town which is conveniently located right in between Spangdahlem Air Force Base and Bitburg city, which is known for its famous beer from the Bitburger brewery and its American military facilities.

The town's name derives from its Latin toponym, villa sacra, which means 'holy town'. The reason for this name was an early church which arose from a Roman temple. In the High Middle Ages Wilsecker was a possession of the Abbey of Prüm. From the Thirty Years' War (1618–1648) until the time of the Kingdom of Prussia (1918) Wilsecker was administrated by the municipality of Kyllburg.

Since 2007 Wilsecker has had a partnership with the 52 EMS Armament Flight Unit of Spangdahlem Airbase. The desire for a partnership was requested by the Americans as an effort to work closely with the local community and point out the typical German small-town lifestyle to American troops.
