Ponta Delgada ("Thin Cape") is the largest municipality (concelho) and economic capital of the Autonomous Region of the Azores in Portugal. It is located on São Miguel Island, the largest and most populous in the archipelago. The population in 2011 was 68,809, in an area of 232.99 square kilometres (89.96 square miles). There are 17,629 residents in the three central civil parishes that comprise the historical city: São Pedro, São Sebastião, and São José. Ponta Delgada became the region's administrative capital under the revised constitution of 1976; the judiciary and Catholic see remained in the historical capital of Angra do Heroísmo while the Legislative Assembly of the Azores was established in Horta.

With a strong concentration of service activities, the municipality is an important industrial and agricultural centre. The Arrifes-Covoada basin is the main bread-basket on the island of São Miguel, in addition to all the parishes located around the rim of the Sete Cidades Massif.

In 1999, 1039 companies had their operational seats within the borders of Ponta Delgada, roughly equal to 45.4% of the companies of the Azores. Of these companies, 4.4% were in the primary sector, 13.7% in secondary industries and 81.9% in the tertiary service sector. The volume of sales (in 2000) was equivalent to 1,458 million Euros, associated with the service industry, of which banking, computer programming/services, corporate and commercial services, as well as tourism, dominate.

Tourist activity in Ponta Delgada accounted for 34% of the hotel occupancy in the region, of which 46% were overnight trips (1997).

In addition, Ponta Delgada is the centre of administrative services in the region, with many of the governmental secretariats located in this municipal seat (including the Regional Presidency and several directorates).

Several newspapers are published in Ponta Delgada, including Açoriano Oriental (one of the oldest continuing daily newspapers in the country) and the Diário dos Açores.
