Hugo de Porta Ravennate was an Italian jurist, and member of the Glossators of Bologna.
Study and teaching at the University of Bologna, Hugo was one of the "four doctors", a group of disciples of Irnerius who were formative in the development of European law.
Their authority was such that the four lawyers were called by Frederick Barbarossa as directors imperial in the diet of Roncaglia in 1158.
This royal patronage allowed them to secure privileges for the newly developing institution of the university, at Bologna.
He wrote the glosses to the recovered Roman law, the distinctiones and Summula de pugna.
