Acquaviva Collecroce (also called Živavoda Kruč or, usually, just Kruč) is a small town and comune in the province of Campobasso, in the Molise region of southern Italy, between the Biferno and Trigno rivers.

Like the smaller towns of Montemitro and San Felice del Molise, Acquaviva Collecroce is home to a community of Molisian Croats, most of whom speak a particular Slavomolisano dialect as well as Italian.

Acquaviva is known for the cultivation of small, dark, zerniza figs, as well as fennel and white celery.

In the 12th century, Acquaviva was a base for the Knights of Malta.

Though there is evidence of an earlier Slavic settlement in 1297, it is believed that the current inhabitants are not their descendants, but rather come from later migrations in the 15th and 16th centuries.
