The Palazzo Bonasoni is a Renaissance-style palace in Via Galliera 21 in central Bologna, Italy.

The site with prior homes belonged originally to the Caccianemici dall’Orso family.

His family had originally been from San Giovanni in Persiceto and Castello d’Argile, but moved to Bologna by 1472.

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.

It still retains a 16th-century fresco, somewhat damaged, which has been variously attributed to either Giovanni Francesco Bezzi or Pellegrino Tibaldi.
