Riomaggiore (Rimazùu in the local Ligurian language) is a village and comune in the province of La Spezia, situated in a small valley in the Liguria region of Italy. It is the first of the Cinque Terre one meets when travelling north from La Spezia.
The village, dating from the early thirteenth century, is known for its historic character and its wine, produced by the town's vineyards. Riomaggiore is in the Riviera di Levante region and has shoreline on the Mediterranean's Gulf of Genoa, with a small beach and a wharf framed by tower houses. Riomaggiore's main street is Via Colombo, where numerous restaurants, bars and shops can be found.
Riomaggiore inspired paintings by Telemaco Signorini (1835–1901), one of the artists of the Macchiaioli group.
