Laredo is a town situated in the autonomous community of Cantabria, Spain. It lies geographically between the major cities of Santander and Bilbao, positioning it within the northern coastal region of the country. The municipality serves as an administrative unit that encompasses not only the main town but also several surrounding villages, including La Arenosa, El Callejo, Las Cárcobas, Las Casillas, and La Pesquera. These settlements are physically integrated into the urban area, contributing to the broader municipal identity of this coastal community.

The settlement's historical roots extend back to Roman times, with its historic town center preserving elements from that era. In 1200, King Alfonso VIII granted Laredo the privilege of becoming a royal town with its own jurisdiction through a charter signed in Belorado. The town played a significant role in regional history, notably serving as one of the departure ports for Jews expelled under the Alhambra Decree in 1492. Its name was later given to the twin cities of Laredo and Nuevo Laredo on the U.S.-Mexico border.

The town is defined by its historic architecture and natural features, most notably La Salvé, a beach stretching five kilometers long, or seven kilometers at high tide. The area is renowned for its well-preserved historic district and its status as one of the main resorts on the Cantabrian coast. The local economy relies heavily on fishing, tourism, and the service sector, with industry focused on processing fishery products like anchovies. It is considered a primary destination for visitors seeking coastal relaxation and cultural heritage.

Cultural life in Laredo is vibrant, particularly during August festivities centered around la batalla de flores, where large floats covered in flowers parade through central streets. Carnival traditions include the Entierro de la Sardina, a ritual where a giant sardine is paraded and burned on the beach after fireworks. The town also hosts various dance, music, and crafts festivals throughout the year at Plaza San Augustin, drawing visitors interested in local customs and community celebrations that highlight its regional identity.

As of 2025, Laredo has a population of 10,698 inhabitants, though earlier records from the 2008 census listed 12,648. The service sector employs over half the population, and average income levels rank among the highest in Cantabria. Transport connections link the town to Bilbao and Santander via Automoviles Luarca, with Madrid accessible by a five-hour bus journey. The region offers moderate winter weather and warm summers, supporting its role as a year-round tourist hub with facilities like the Laredo Regional Hospital serving the surrounding area.
