The Palazzo Bonasoni is a Renaissance-style palace in Via Galliera 21 in central Bologna, Italy. It stands across the street from the Palazzo Felicini. The site with prior homes belonged originally to the Caccianemici dall’Orso family. By the mid-16th century, it was acquired by the rising nobleman Galeazzo Bonasoni. His family had originally been from San Giovanni in Persiceto and Castello d’Argile, but moved to Bologna by 1472. Galeazzo's father had been a docent in canon law at the University of Bologna. In 1544, Galeazzo had been named knight and Count Palatine by the Holy Roman Emperor Charles V. Documents suggest that in 1556, Galeazzo employed the architect Antonio Morandi, known like his father as il Terribilia, to help design the palace.
