Pietro Aglieri (Italian pronunciation: ['pj??tro a?'???ri]; born June 6, 1959 in Palermo) is a Sicilian mafioso from the Guadagna neighbourhood of Palermo.
He is known as 'u Signurinu ("The Little Gentleman") for his relatively sophisticated education and refined manners.
He had a classical education and studied Greek, Latin, philosophy, history and literature to a level that guaranteed him entry to university.
Instead he chose for a career in Cosa Nostra.
The British journal The Guardian listed him as the emerging man of the year 1995 in Italy.
