Chiavari (Italian pronunciation: [ˈkjaːvari]; Ligurian: Ciävai [ˈtʃaːvaj]) is a seaside town and municipality in the Metropolitan City of Genoa in the region of Liguria in Italy. As of 2025, with a population of 27,442, it is the 3rd-largest municipality in the metropolitan city and the 7th-largest in Liguria.

It has a beachside promenade and a marina and is situated near the river Entella.

A pre-Roman necropolis, which dates from the 8th to 7th century BC, has been uncovered in the area where Chiavari is located now. Chiavari grew up on the traces of a Roman camp on the Via Aurelia.

A castle was constructed in 1147. The old town contains numerous arcades and buildings from the 13th century, including a castle, several mansions, and the nearby Church of San Salvatore di Lavagna, which was founded in 1224 by Innocent IV.

The cathedral was rebuilt in 1613. Famous as a center of humanism, Chiavari has a public library with a collection of manuscripts and incunabula. After the discovery of the conspiracy of the Fieschi, in 1542, and the capture of Chiavari by the Counts of Lavagna, the town suffered greatly, being associated with the conspirators. Among its illustrious citizens were Luca Cantiano di Moneglia, founder of an art academy, and Giuseppe Gregorio Solari, translator of many Latin poets.

From 1805 to 1814, Chiavari served as the capital of the short-lived Apennins Departments of France of the First French Empire. Chiavari is the home of the Chiavari chair designed in 1807 by a local, Giuseppe Gaetano Descalzi. The chair was a success and led to the opening of many factories in Chiavari and surrounding towns.

Chiavari railway station was opened in 1868; it provides an underground passageway between the town centre and the beachside promenades.

The Colonia Fara building was built in 1935 during the Fascist regime.
