Pavle Matejić (Serbian Cyrillic: Павле Матејић; c. 1770–1816), known as Paulj (Пауљ Матејић), was a Serbian Revolutionary that participated in the First Serbian Uprising (1804–13). Starting out as a captain under the command of Petar Dobrnjac, Paulj was elevated to vojvoda (general) in the Gornja Mlava region upon showing his courage. He took part in the successful campaigns in the eastern parts of the Belgrade Pashaluk, and the campaign to take Niš (1809).
He was born in the village of Melnica, at that time part of the Požarevac nahiya in the Sanjak of Smederevo ("Belgrade Pashaluk").
He became a buljubaša (captain) already by the beginning of the uprising, appointed by Petar Dobrnjac. For his courage and other great traits, he was later appointed vojvoda (general) in Gornja Mlava. Paulj participated in the victories in the eastern parts of the Belgrade Pashaluk that strengthened rebel holding.
A rebel army led by commanders Miloje Petrović, Petar Dobrnjac, Ilija Barjaktarević, Paulj Matejić, Stevan Sinđelić and Veljko Petrović arrived on 27 April [O.S. 15 April] 1809 outside Niš. During preparations for the takeover of Niš, Paulj made a trench above the village of Kamenica. The trench, above the church, had two cannons. It was one of eleven or twelve rebel trenches around the city. On 31 May [O.S. 19 May], when the Ottomans rushed on the Čegar hill defended by Stevan Sinđelić, and vojvoda Miloje did not let anybody aid them, Paulj decided against the command and went for Čegar. Paulj did not reach in time; when the Ottomans had surrounded and overtook Sinđelić's trench, he decided to blow up the gunpowder magazine and kill everyone on the hill. Paulj and his small unit were defeated and forced to retreat, as others, to Deligrad. He mostly stayed in Deligrad after this. The Serbian Ruling Council appointed Paulj the first permanent commander of Gurgusovac (Knjaževac) after the Treaty of Bucharest (1812).
