Saint Soteris was a Roman virgin and martyr, who was put to death for her faith in the early 4th century.^[1] She is venerated in the Roman Catholic church on 11 February and in the Eastern Orthodox Church on 10 February.

Soteris was supposedly a woman of very great beauty, who dressed modestly and consecrated her virginity to Christ.^[1] She was arrested on account of her faith, and underwent torture, before being finally beheaded, perhaps around AD 304.^[2][3][4]

Her remains were buried in the Catacombs of Callixtus in the 3rd century along the Appian Way as it approached Rome, which also contained the remains of Saint Cecilia and many other martyrs.^[5] In the same region was dedicated a basilica to Saint Soteris.^[6]

Saint Ambrose of Milan claimed that he, his older sister Saint Marcellina, and their brother Saint Satyrus, descended from Soteris' family, and he wrote about her.^[2]
