Dolceacqua is a comune (municipality) in the Province of Imperia in the Italian region Liguria, located about 120 kilometres (75 mi) southwest of Genoa and about 35 kilometres (22 mi) west of Imperia, on the border with France. As of 31 December 2014, it had a population of 2,078 and an area of 20.2 square kilometres (7.8 sq mi).

Dolceacqua borders the following municipalities: Airole, Apricale, Breil-sur-Roya (France), Camporosso, Isolabona, Perinaldo, Rocchetta Nervina, San Biagio della Cima, and Ventimiglia.

In Dolceacqua is located the Pinacoteca Giovanni Morscio. The museum was founded in 1970, thanks to a donation by the local painter Giovanni Morscio of paintings of him and other Italian and French painters of his time.

Morscio (1887-1972) was mainly devoted to still life and frescos; he was active in Liguria and Nice, and he exhibited at the Salon des Indépendants in 1930 and practiced in France also as a gallery owner.

The collection was enlarged by the municipal administration in the eighties. After an initial location in the former town hall, the museum was transferred to the Doria Garoscio Palace.

The original collection is focused on a selection of works by Morscio and some Italian and French painters of his time: Eloi Noël Bouvard, Mario Ameglio, Eugenio Bonivento, Cyrano Castelfranchi, Georges Chappuis, Gaston Cirmeuse, Yves Diey, Robert Duflos, Charley Garry, Maurice Martin, Maurice Louis Monnot, Fernando Pelosini, Alberto Rossi, André Salomon Le Tropezien.

After Morscio's death collection has been enlarged with paintings by Achille Cabiati, Marcello Cammi, Franco Giglio and Mario Raimondo.
