Kronan, also called Stora Kronan, was a Swedish warship that served as the flagship of the Swedish Navy in the Baltic Sea in the 1670s. When built, she was one of the largest seagoing vessels in the world. The construction of Kronan lasted from 1668 to 1672 and was delayed by difficulties with financing and conflicts between the shipwright Francis Sheldon and the Swedish admiralty. After four years of service, the ship foundered in rough weather at the Battle of Öland on 1 June 1676: while making a sharp turn under too much sail she capsized, and the gunpowder magazine ignited and blew off most of the bow. Kronan sank quickly, taking about 800 men and more than 100 guns with her, along with valuable military equipment, weapons, personal items, and large quantities of silver and gold coins.

The Battle of Öland was a naval battle between an allied Danish-Dutch fleet and the Swedish navy in the Baltic Sea, off the east coast of Öland on 1 June 1676. The battle was a part of the Scanian War (1675–79) fought for supremacy over the southern Baltic. Sweden was in urgent need of reinforcements for its north German possessions; Denmark sought to ferry an army to Scania in southern Sweden to open a front on Swedish soil.
