Luigi Antonio Lanzi (13 June 1732 – 31 March 1810) was an Italian Jesuit priest, known for his writings as an art historian and archaeologist.

In the one field his labors are represented by his Storia Pittorica dell' Italia, the first portion of which, containing the Florentine, Sienese, Roman and Neapolitan schools, appeared in 1792, the rest in 1796.

In his 1806 memoir on the so-called Etruscan vases Dei vasi antichi dipinti volgarmente chiamati Etruschi, Lanzi rightly perceived their Greek origin and characters.

He was allied with Ennio Quirino Visconti in his great but never accomplished plan of illustrating antiquity altogether from existing literature and monuments.

His notices of ancient sculpture and its various styles appeared as an appendix to the Saggio di lingua Etrusca, and arose out of his minute study of the treasures then added to the Florentine collection from the Villa Medici.
