The County of Besalú (Catalan: Comtat de Besalú, IPA: [kumˈtad də βəzəˈɫu]; Latin: Comitatus Bisuldunensis) was one of the landlocked medieval Catalan counties near the Mediterranean coastline. It was roughly coterminous with the modern comarca of Garrotxa and at various times extended as far north as Corbières, Aude, now in France. Its capital was the village of Besalú. Throughout most of its history it was attached to one of the other more powerful counties, but it experienced a century of independence before it was finally and irrevocably annexed to the County of Barcelona.
Besalú was reconquered from the Moors by 785. It was originally a pagus of the County of Girona in the Marca Hispanica. The original pagus comprised the territories of Garrotxa and those neighbouring Montgrony and Setcases in the comarca of Ripollès as far as Agullana and Figueres (in Alt Empordà) and Banyoles in Pla de l'Estany.
