Põhja-Kõrvemaa Nature Reserve (Estonian: Põhja-Kõrvemaa looduskaitseala) is a protected area in Harju County, Northern Estonia, some 50 km east of Tallinn. With an area of 130.9 km2, it is the third largest nature reserve in Estonia. Dominated by forests and bogs, it aims to protect rare and endangered species, their habitats, and valuable natural landscapes.

Põhja-Kõrvemaa (meaning North Kõrvemaa) occupies the northern part of Kõrvemaa, which itself forms the northern part of Transitional Estonia, a large forested and sparsely populated area spanning in northeast-southwest direction through Estonia, from Lahemaa through Soomaa to Latvia.
