Alvintzi, Peter a Hungarian Protestant ecclesiastic of the 17th century, was born in Transylvania. He completed his studies at the best universities of Switzerland and Germany, and became pastor in Hungary. His religious zeal led him into a warm controversy with the Jesuit Peter Pazmany, archbishop of Gran. He wrote in the Hungarian language a number of controversial works, among which we notice one published in 1616, entitled The Catholic Itinerary, in which the author compares the two religions, the Protestant and the Catholic. He also composed a Hungarian Grammar. See Hoefer, Nouv. Biog. Generale, s.v.
