Sucs (Catalan pronunciation: [ˈsuks] previous spelling Suchs, still prevalent in Spanish, but controversial and not official) is a locality in the municipality of Lleida (Catalonia, Spain). Like the neighbouring Raimat, the official status of Sucs is that of a decentralised municipal entity, as some semi-urban wards attached to a larger municipality are known in Catalonia, and located 22 km from Lleida. In the 2008 census Sucs had 578 inhabitants. Its name comes from Arabic, and is a reference to the local fair. It's mentioned in 1188, in the Ordinato Ecclesia Ilerdensis, as part of the bishopric of Lleida, along with the neighbouring locality of Suquets.^[1]

The ruins of Sucs castle and a Romanesque church dating back from the 12th century are located on top of a hill known as Lo Vilot.
