København (Copenhagen) was a Danish owned, British-built five-masted barque used as a naval training vessel until its disappearance after 22 December 1928. Built for the Danish East Asiatic Company in 1921, it was the world's largest sailing ship at the time, and primarily served for sail training of young cadets.

Ramage & Ferguson was a Scottish shipbuilder active from 1877 to 1934, who specialised in luxury steam-yachts usually with steel hulls and timber decks. They also made several notable windjammers including the stunning five-masted København.
