Subiaco is a comune (municipality) in the Metropolitan City of Rome Capital, in the Italian region of Latium, 40 kilometres (25 mi) from Tivoli alongside the River Aniene. It is a tourist and religious resort because of its sacred grotto, in the medieval St. Benedict's Abbey, and its Abbey of Santa Scolastica. It is one of I Borghi più belli d'Italia. The first books to be printed in Italy were produced here in the late 15th century.

I Borghi più belli d'Italia is a non-profit private association of small Italian towns of strong historical and artistic interest, that was founded in March 2001 on the initiative of the Tourism Council of the National Association of Italian Municipalities, with the aim of preserving and maintaining villages of quality heritage. Its motto is Il fascino dell'Italia nascosta.
