Manke Nelis, born Cornelis Pieters, was a Dutch singer in the levenslied genre.
Manke Nelis was born in Amsterdam on 16 December 1919 and began his musical career as a bass player, often accompanying his cousin, accordionist Johnny Meijer. In the 1950s he performed under the stage name Carlo Pietro and started singing the Amsterdam levenslied. A motorcycle accident in France and a subsequent medical error cost him a leg; he reportedly spent the more than 100,000 guilders he received as compensation within a year. His biggest hit was "Kleine Jodeljongen" in 1987.
In 1987 he narrowly survived a bus crash on an American tour with Dutch artists, near San Diego. He died of cancer 8 October 1993, at age 73.
A statue of Manke Nelis was placed on the Johnny Jordaan Square off the Elandsgracht, in the company of statues for Johnny Jordaan, Tante Leen, and Johnny Meijer. His song "Ze zeggen dat ik een schooier ben" is sampled at the end of the Osdorp Posse song "Origineel Amsterdams" (2000).
