Solsona (Catalan pronunciation: [sulˈsona]) is a municipality and capital of the comarca of the Solsonès in the province of Lleida, Catalonia, Spain.

Until a few years ago, Solsona used to be the main road used by people from Barcelona to go to Andorra.

The name most probably derives from the Setelsis (Ancient Greek: Σετελσίς or Σελενσίς) mentioned by Ptolemy as a town of the tribe of Iacetani in Hispania Tarraconensis.

The cathedral of Santa Maria de Solsona and the episcopal palace are in a neoclassical style.

One of the most important events in the city is Carnaval, a pagan celebration that marks the beginning of the Quaresma.
