Prota Mateja Nenadović (1777 – 1854) is a Serbian archpriest, writer, and a notable leader of the First Serbian Uprising.

He is generally called Prota Mateja, since as a boy of sixteen he was made a priest, and a few years later became archpriest (prota) of Valjevo.

His father, Aleksa Nenadović, Knez (chief magistrate) of the district of Valjevo, was one of the most popular and respected public men among the Serbs at the beginning of the 19th century.
