Isla Contadora (or Contadora Island in English) is a Panamanian island on the Pearl Islands archipelago (Spanish: Archipielago de las Perlas) in the Gulf of Panama. It has an area of 1.39 km², which makes it the 11th largest island of the archipelago. With a population of 253 (census 2000), however, it ranks third, after Isla del Rey and Isla Taboga. A popular tourist destination, Contadora has a small regional/domestic airport (IATA code: OTD), and has regular flights to and from Panama City and the rest of the islands in the archipelago.
Contadora was the island where the Spanish counted the pearls that were harvested from the other islands in the archipelago, hence the name of the island, which means "the one that counts" in Spanish. The islands produced pearls of many colors and sizes, and during the many years when pearls were harvested from the waters around the islands, the natives would converge to Contadora to count their pearls and sell them to the Spaniards. Early last century there was an underwater epidemic which killed most of the pearl oysters, reducing the production of pearls to a dribble.
