Cadaqués is a town in the Alt Empordà comarca, in the province of Girona, Catalonia, Spain. It is on a bay in the middle of the Cap de Creus peninsula, near Cap de Creus cape, on the Costa Brava of the Mediterranean. It is only a two-and-a-quarter-hour drive from Barcelona, and thus it is very accessible and not only attracts tourists but people who want a second home for weekends and summers. In 2002, Cadaqués had an official population of 2,612, but up to ten times as many people can live in the town during the peak of the summer tourism season.

Cadaqués has a special place in art history. Commanding charcoals, by local artist Eliseu Meifrèn, of the 19th century Cadaqués beleaguered by a winter tramontane, can be seen at the Cadaqués museum. Fren was the first modern artist to live in Cadaqués and gave the town many of his works and a marble top table on which he sketched many of its turn-of-the-century fishermen.

Salvador Dalí often visited Cadaqués in his childhood, and later kept a home in Port Lligat, a small village on a bay next to the town. A summer holiday here in 1916, spent with the family of Ramon Pichot is seen as especially important to Dalí's artistic career. Other notable artists, including Pablo Picasso, Joan Miró, Marcel Duchamp, Richard Hamilton, Albert Ràfols-Casamada, Antoni Pitxot, Henri-François Rey, Melina Mercouri and Maurice Boitel also spent time here. Cadaqués is mentioned in the story "Tramontana" by Gabriel García Márquez.

The interesting submarine life of this sleepy fishing village was studied for several years by phycologist Françoise Ardré, long before Cadaqués was discovered and transformed into a tourism destination. On Mondays there is a travelling market in Cadaqués, located near the parking lot. This market has a wide variety of products.

In the early 20th century a large number of inhabitants of Cadaqués travelled or emigrated to Cuba (the figure has been estimated as one third of a village of approximately 1200 people). Many of these immigrants were financially successful in Cuba and returned to Cadaqués where they constructed large and ornate houses. These houses can still be seen in the town (for example; the "Casa Blava", "Blue House" in English). A person returned from Cuba was referred to as an "Americano" among other names.
