Stefan Crnojević (Serbian Cyrillic: Стефан Црнојевић, 1469–1499), or Stephen II[2] was a nominal ruler of the Principality of Zeta between 1496 and 1499.

Until 1496, the ruler of Zeta had been Stefan's older brother Đurađ Crnojević, who maintained frequent correspondence with other Christian feudal states with intention to establish an anti-Ottoman coalition.

[4] Stefan remained in Zeta hoping that the Ottomans would accept his suzerainty, but they only used him in order to easier gain control over his domains.

[6] In 1497 Feriz Beg captured Grbalj and put it under his effective military control, although it was still part of Zeta governed by Stefan Crnojević.

[8] According to some authors, after his brother had fled Zeta, Stefan was only an Ottoman spahi, who in 1499 went to Hilandar and became a monk, taking the monastic name Marko.
