Ribera (Sicilian: Rivela) is a comune in the province of Agrigento, Region of Sicily, southern Italy, between the Verdura and Magazzolo valleys in the so-called Plain of San Nicola.

The comune probably rose on the site of the ancient Allava, to which the Byzantine necropolis near the modern town may possibly be attributed.

Sights include: Just outside the town, on a gorge overlooking the Verdura river is the Castello di Poggio Diana, built by Guglielmo Peralta in the 14th century.

It includes some 30 tombs in two types, "chamber"- or "grotto"-like; some are preceded by a corridor up to 4 metres (13 ft) long.

Agriculture is the commune's main industry, notably involved in the cultivation and marketing of the Washington navel orange – here introduced by emigrants returned from the United States – and strawberries.
