Ledringhem is a commune in the Nord department in northern France.

It is situated also in the ancient territory of the French Flandre, in the Houtland (or woodland, with the cities of Cassel and Hazebrouck) in the Franse Westhoek (French Western corner) where Flemish was still spoken until recently.

The residents of Ledringhem are called Ledringhemois.

The village is about 4 kilometres (2.5 mi) southwest of the small town of Wormhout, and approximately 10 kilometres (6.2 mi) north of Cassel. Bigger cities are Dunkirk further to the north and Hazebrouck further to the south.

Ledringhem is crossed by the small river Peene Becque, a tributary of the Franco-Belgian river Yser and there is one shorter tributary, the Lyncke Becque, passing closer to the village center. Other small rivers are Trommels Becque, Putte Becque, Platse Becque and Kaliszewski Becque.

The climate in Ledringhem is oceanic with a mild summer (Köppen Classification : Cfb).
