Kriwe Kriwaito or simply Kriwe was the chief priest in the old Baltic religion. Known primarily from the dubious 16th-century writings of Simon Grunau, the concept of kriwe became popular during the times of romantic nationalism. However, lack of reliable written evidence has led some researchers to question whether such pagan priest actually existed. The title was adopted by Romuva, the neo-pagan movement in Lithuania, when Jonas Trinkūnas was officially installed as krivių krivaitis in October 2002.

Romuva is a neo-pagan movement derived from the traditional mythology of the Lithuanians, attempting to reconstruct the religious rituals of the Lithuanians before their Christianization in 1387. Practitioners of Romuva claim to continue Baltic pagan traditions which survived in folklore, customs and superstition. Romuva is a polytheistic pagan faith which asserts the sanctity of nature and ancestor worship. Practicing the Romuva faith is seen by many adherents as a form of cultural pride, along with celebrating traditional forms of art, retelling Baltic folklore, practicing traditional holidays, playing traditional Baltic music, singing traditional dainos (songs), as well as ecological activism and stewarding sacred places.
