Måns Nilsson Kling or Mauno Kling was the second governor of the 17th century colony of New Sweden (Swedish: Nya Sverige), which he administrated from Fort Christina, now Wilmington, Delaware.
The first Swedish expedition to North America with Fogel Grip and Kalmar Nyckel was launched from the port city of Gothenburg in late 1637. The expedition was organized and overseen by Swedish Admiral Clas Fleming. Samuel Blommaert, a Dutch colonial patron, assisted with the fitting-out. Following the recommendation of Willem Usselincx, one of the directors of the Dutch West India Company, Swedish Chancellor Axel Oxenstierna appointed Peter Minuit to lead the expedition. Minuit made arrangements to found a Swedish colony on the lower Delaware River in parts of the present-day states of Delaware, New Jersey, and Pennsylvania, within the territory later claimed by the Dutch. The first settlers, (Swedes, Finns, and some Dutchmen) reached the location now known as Swedes' Landing in Wilmington, Delaware on March 29, 1638. Peter Minuit became the first governor of the newly established colony of New Sweden. However, Minuit left the colony on June 15, 1638 and sailed to the Caribbean Island of St. Christopher to barter a ship's cargo of wine and aquavit for tobacco. Minuit died there during a hurricane.
Måns Kling had arrived with the first expedition and was left in command of New Sweden following the departure of Peter Minuit. Kling, who had been promoted to Captain, carried out the duties of governor until Lieutenant Peter Hollander Ridder of the Swedish Navy, arrived in New Sweden on April 17, 1640.
