Waltrop (German pronunciation: [ˈvaltʁɔp] ⓘ is a town in the district of Recklinghausen, in North Rhine-Westphalia, Germany.

The town of Waltrop is surrounded by the Bauerschaften (rural boroughs) Lippe (Unterlippe/Oberlippe), Elmenhorst, Brockenscheidt, Leveringhausen, Oberwiese and Holthausen.

The village developed around the parish church of St. Peter which was built in the 9th/10th century.

After the Soest Feud, the archbishops of Cologne could intervene against the counts of Mark, so that Waltrop became a part of Vest Recklinghausen.

Waltrop is home to a museum of old ship lifts, including the Henrichenburg boat lift and a historical coal mine, called Zeche Waltrop.
