Mrkojevići (Montenegrin and Serbian Cyrillic: Мркојевићи), also known as Mrkovići (Мрковићи), was a historical tribe in southeastern Montenegro, located between the towns of Bar and Ulcinj. The region covers an area of 91.06 km², of which 77.09 km² falls in the territory of the Municipality of Bar while 13.97 km² falls in the territory of the Municipality of Ulcinj.
