The Massif du Nord (French pronunciation: [masif dy nɔʁ]) is the longest mountain range of Haiti.

[2] The mountain range is located in the northern region of Haiti, in the departments of the Nord and in Artibonite.

The Plaine-du-Nord lies along the northern border with the Dominican Republic, between the Massif du Nord and the North Atlantic Ocean.

A narrow northern coastal plain lies north of the range on the Caribbean Sea.

[5] The Massif du Nord separates the city of Cap-Haïtien from the capital Port-au-Prince.
