Ulla Winblad is a semi-fictional character in many of Carl Michael Bellman's musical works. She is at once an idealised rococo goddess and a tavern prostitute, and a key figure in Bellman's songs of Fredman's Epistles. The juxtaposition of elegant and low life is humorous, while allowing Bellman to convey a range of emotions. Ulla Winblad has been called "one of the really great female figures in Swedish literature". The character was partly inspired by Maria Kristina Kiellström (1744–1798).

Carl Michael Bellman was a Swedish songwriter, composer, musician, poet, and entertainer. He is a central figure in the Swedish song tradition and remains a powerful influence in Swedish music, as well as in Scandinavian literature, to this day. He has been compared to Shakespeare, Beethoven, Mozart, and Hogarth, but his gift, using elegantly rococo classical references in comic contrast to sordid drinking and prostitution—at once regretted and celebrated in song—is unique.
