The Battle of Vuelta de Obligado took place on 20 November 1845, in the waters of the Paraná River, on its right bank and in the north of the province of Buenos Aires (Argentina), in a bend where the river narrows and turns, known as Vuelta de Obligado, in what is today the town of Obligado (San Pedro district).

It confronted the Province of Buenos Aires, led by Brigadier Juan Manuel de Rosas - who appointed General Lucio Norberto Mansilla as commander of the Buenos Aires forces - and the Anglo-French squadron, whose intervention was carried out under the pretext of achieving pacification in the face of the problems existing between Buenos Aires and Montevideo. The Europeans intended to establish direct trade relations between Britain and France with the provinces of Santa Fe, Entre Ríos and Corrientes, without going through Buenos Aires or recognizing Rosas' authority as the person in charge of foreign relations for the Argentine Confederation.
