Cartagena’s economy is largely driven by its port, one of Spain’s key maritime hubs for both commercial and military purposes. The city’s naval base is an important center for the Spanish Navy, while the commercial port supports industries such as mining, fishing, and trade. The petrochemical industry also plays a significant role, with Cartagena housing one of the largest oil refineries in Spain.
Tourism is another major economic driver, with visitors attracted by the city’s historical sites, beautiful coastline, and year-round pleasant climate. The Mar Menor, a saltwater lagoon located nearby, is a popular destination for water sports enthusiasts, contributing to the growth of the tourism sector. Local businesses also thrive on agriculture, with the surrounding Murcia region known for its production of fruits, vegetables, and wines.
Local craftsmanship and products, such as pottery, textiles, and jewelry, add to the city’s economic landscape. Markets and shops selling handmade goods are common, particularly in the city’s historic quarter.
