The name
Selkup (Russian ''sel'kupy'' (plural)) was originally a self-designation of one group of Northern Selkups in the
Taz River basin, but came to be applied to all the other local groups between the 1930s and 1980s. In Russian, the Selkup used to call themselves
Ostyak. This name is originally an
exonym originating from the 17th century, when it was used to denote the
Ob-Ugrian and
Samoyed population of the Middle
Ob region. By the end of the 20th century the name had been adopted by the Selkup as an
endonym. In the scientific literature from 1850s until the 1930s, the Selkup were exclusively called Ostyak-Samoyeds (
остяко-самоеды, ostyako-samoyedy). This ethnonym has never been widely used. == Language ==
