Helena Pedersdotter Strange (Danish: Helene; in Sweden also called Queen Elin; c. 1200–1255) of a Danish noble family later called Ulfeldt was a Queen of Sweden as the wife of King Canute II.
She is believed to have married the Swedish regent Canute in about 1225, though the exact year is not known.
She used the same seal as her husband on official documents, a curious fact which indicates that she may have exerted some political influence.
Queen Dowager Elin remarried the nobleman Filip Lauresson.
In 1247, she witnessed her son from her first marriage rebel against the new monarch; he failed, and was executed in 1248.
