Adelfia (Greek: Αδέλφια, meaning brothers; Barese: Adélfie) is a town and comune in the Metropolitan City of Bari, Apulia, southern Italy.

The urban center includes two former villages that were separated for a long time.

Canneto was founded by the Normans of Robert Guiscard between 1080 and 1090, on the place of an ancient center (probably to be identified with Celiae), documented from ceramics and more recent graves from the 4th century.

The two villages were united in 1927 under the artificial name of Adelfia, from the Greek term adelphòs, meaning brotherhood.

The celebrations include fairs, masses and fireworks competitions which attract thousands of pilgrims from all over the world.
