Kategoria e Tretë (transl. Third Category) is the fourth and lowest professional level of football in Albania's football league system. In the 2023−24 season, Kategoria e Tretë has 15 teams participating, split in 2 groups. The winners of each group earn the right to be promoted to the Kategoria e Dytë and play a final match to determine the champions. The runners-up of each group qualify to the play-off round. For the first time in this championship, the matches will be played with a round-robin system, unlike in previous years, which were all held in the field of the national team in Kamza, Tiranë.
