Maiden Creek is a 32.7 km tributary of the Schuylkill River in Berks County, Pennsylvania. The name Maiden is an English translation of the Native American word Ontelaunee. Maiden Creek is formed by the confluence of Ontelaunee and Kistler creeks in the community of Kempton. The tributary Sacony Creek joins at the community of Virginville.
The creek was dammed in 1926 to form Lake Ontelaunee. The creek joins the Schuylkill River north of the city of Reading, for which it serves as the main drinking water supply.
