Felicula was a Christian martyr living in Rome during the fourth century. According to the Roman Martyrology, her remains were located near the seventh milestone of the Via Ardeatina. While historical records place her in the fourth century, certain legendary accounts, such as the romanticized Acts of Saints Nereus and Achilleus, suggest she lived much earlier, around 90 AD. In these traditional narratives, she is identified as a virgin martyr and the foster sister of Saint Petronilla.
