Giulio Negrone or Iulius Nigronius (1553-1625) was a Jesuit humanist orator and scholar, who also wrote under the name Panfilo Landi.

[1] As Rector of the Accademia Partenia of Rome, he wrote a treatise on the chain impresa of the academy, emphasising its Neoplatonic and Christian connotations.

[2] He was a professor of rhetoric, philosophy and theology at Milan and Genoa, afterwards serving as rector of the Verona, Genova and Cremona colleges.

He undertook with Claudio Acquaviva's approbation a copious ascetical commentary on the Common Rules (Regulae Communes Societatis Iesu), published in Milan in 1613.

A staunch Ciceronian, Negrone was the author of a number of rhetorical works.
