The Llobregat (Catalan pronunciation: [ʎuβɾəˈɣat]) is the second longest river in Catalonia, Spain, after the Ter. It flows into the Mediterranean south of the city of Barcelona. Its name could have originated in an ancient Latin word meaning dark, muddy or slippery, or simply from its ancient name Rubricatus, literally red. It is 170 km long.
