Nils Stensson Sture (1512 – 1526 or 1528), born 1512, was the eldest son and heir of Sten Sture the Younger. The so-called Daljunkern ('the Dale-Junker', i.e. the junker from Dalarna), the young leader of an unsuccessful rebellion against Gustav Vasa, claimed to be Nils Sture, and it is a much-discussed question in Swedish historiography whether they really were the same person or if Daljunkern was an impostor.
