Chiaro de Fialis (died 1479) was a Borgia messenger who lived in Renaissance Italy. De Fialis was sent to collect and deliver payments to Templar allies by Grand Master Rodrigo Borgia, and he was sent to Florence in 1479 in the aftermath of the Pazzi Conspiracy. De Fialis was sent to give money to some Pazzi allies, but he was chased down and assassinated by Ezio Auditore da Firenze, who proceeded to hide his body.
