Juliana Olshanskaya (c. 1525 – c. 1540; Ukrainian: Юліанія Юріївна Ольшанська Дубровицька, romanized: Yulianiia Yuriivna Olshanska Dubrovytska) was a member of the Olshanski noble family who became a saint in the Eastern Orthodox Church.

The early 17th-century Archimandrite Peter Mogila claimed to have had a vision of Saint Juliana in which she reproached him for a lack of respect given to her relics.

Juliana Olshanskaya was the daughter of Prince Yurii (also Georgy) Dubrovitsky-Olshansky of the Olshanski family who ruled part of modern Ukraine.

[3] Juliana's body was discovered during the time of Archimandrite Elisey Pletenetsky (in office 1599–1624), whilst digging a grave for the burial of another virgin.

[3][4] After opening a coffin that lay beneath a stone marked with her name and the Olshanski coat of arms, her body was said to be in a state of incorruptibility.
