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.Mazza's beatification process opened in the 1920s and culminated on 3 June 2013 after Pope Francis confirmed his heroic virtue and named Mazza as Venerable.
