Viking is a four-masted steel barque, built in 1906 by Burmeister & Wain in Copenhagen, Denmark. She is reported to be the biggest sailing ship ever built in Scandinavia. In the 21st century her sailing days have drawn to a close, and she is now moored as a botel in Gothenburg, Sweden.

Gustaf Adolf Mauritz Erikson was a ship-owner from Mariehamn, in the Åland islands. He was famous for the fleet of windjammers he operated to the end of his life, mainly on the grain trade from Australia to Europe.
