Cornelis Vreeswijk (Swedish pronunciation ; Dutch pronunciation ; 8 August 1937 – 12 November 1987) was a Dutch-born Swedish singer-songwriter, poet and actor.
He emigrated to Sweden with his parents in 1949 at the age of twelve. He was educated as a social worker and hoped to become a journalist, but became increasingly involved in music, performing at events for students with idiosyncratic humor and social engagement. Cornelis Vreeswijk is considered one of the most influential and successful troubadours in Sweden. In 2010 a Swedish drama film, called Cornelis, was made about his life. It was directed by Amir Chamdin.
