Bollezeele (French pronunciation: [bɔlzɛl]; from Dutch; Bollezele in the modern Dutch spelling) is a commune in the Nord department in northern France.

The river Yser runs through Bollezeele.

Bollezeele's local speech is traditionally a Flemish dialect, similar to that spoken on the other side of the border with Belgium; this led to the town's being included in the Atlas Linguarum Europae as one of the Germanic dialects in France (the others were all in either Alsace or Moselle).

('Flanders' and the communes of Thourotte, Crépy-en-Valois, Bollezeele, Feignies, Flines-lez-Raches and Wormhout use the same arms.)
