Kullaberg () is a peninsula and nature reserve of land protruding into the Kattegat in Höganäs Municipality near the town of Mölle in southwest Sweden. The site in the province of Skåne is an area of considerable biodiversity supporting a number of rare species and has been designated as an Important Bird Area (IBA) in Sweden as well as a Special Protection Area (SPA). The terrain is dominated by steep cliffs rising from the sea and rocky outcrops on the ridge above, the highest elevation being Mount Håkull at 188 meters. Ridgetop vegetation includes a mixed hardwood broadleaf forest consisting of birch, beech, oak and pine trees with an understory of hawthorn, juniper, wild honeysuckle and blackthorn. Among the notable rare plants are spring vetchling, "Lathyrus sphaericus".
