L'Estartit (Catalan pronunciation: [lestaɾˈtit]; Spanish: Estartit) is a small town and seaside resort on the Costa Brava, part of the municipality of Torroella de Montgrí in the Baix Empordà county, Girona province, autonomous community of Catalonia, Spain.

Initially a fishing village, the advent of tourism in the Costa Brava from the 1960s onwards brought a large influx of visitors to the town during the summer months.

The community grew exponentially for the next two decades, initially with houses and villas built up the hills that surround the harbor, and later with hotels, apartment blocks, and campsites extending along the beach and the flood plain of the Ter estuary.

Tourists visiting L'Estartit originate mainly from France, the United Kingdom, Ireland, Germany and the Netherlands, with significant numbers coming from Barcelona for the weekend too, whilst the majority of the labor force hails from the south of Spain, especially Andalusia and Extremadura.

Like many other tourist resorts around the world, massification and uncontrolled growth led the town to lose the charm that had made it popular in the first place.
