Piadena (Italian pronunciation: [ˈpjaːdena]; Eastern Lombard: [ˈpjadenɔ]) is a former comune in the Province of Cremona, Italy.

In the Neolithic, primitive peoples lived in huts located on high ground and in lake settlements in the Bronze Age.

The locality is mentioned in a 990 deed by which the Cremonese bishop donated the castle to the Monastery of San Lorenzo in Cremona.

After being occupied by the Gonzagas, it was passed to the Visconti in 1348, who improved its defenses and erected watchtowers (the "torrazze di Salvaterra"), which can still be seen on the local coat of arms.

During the 18th and 19th centuries,Piadena shared the fate of the rest of the Lombard territory, from the first Habsburg rule, to the advent of Napoleon, and the establishment of the Lombard-Venetian Kingdom.

In the town hall, which occupies the former Gerolimini convent, there is an archaeological museum displaying numerous prehistoric, Celtic and Roman artifacts.

"Coat of arms in silver, to the two covered towers, gules, bricked and windowed in black, united by the bridge in gules, bricked in black, with convex scaffolding, founded on the plain in azure, floating in silver, these towers accompanied at the point of honor by the waving bison in pole, azure, crowned in the ancient style in gold, engulfing the putto of flesh, hairy in black, with arms outstretched.

Under the shield, on a bifid, fluttering list of silver, the motto, in capital letters of black, PROSPERA ET PROBATA PLATINA.
