The N3 road also designated as RN3, is a national route in Central African Republic spanning 437 kilometers in length.

It forms an east–west axis in the western region of the country, connecting Bossembélé to the border with Cameroon at Garoua-Mboulaï.

The route facilitates transportation and trade between the Central African Republic and Cameroon, traversing diverse landscapes and regions in the western part of the country.

The final phase, completed in 2020, involved paving the section between Baoro and Bouar, thereby establishing a fully asphalted connection between Bangui and the Cameroonian seaport of Douala via the N3 route.
