Nicola Mazza (10 March 1790 – 2 August 1865) was an Italian Roman Catholic priest. Mazza was born in and served as a priest in Verona and was dedicated to both the evangelization of Central Africa (he used to be called "Don Congo" due to this) and equal access to a good education. He served as a teacher for over three decades as well as a chaplain and was known for his dedication to the Christian formation of children. Mazza was also a student and close friend to Saint Gaspare Bertoni and was also close with a range of prominent prelates including Saint Daniele Comboni whom he sent to the missions in Africa.
