Mangayarkkarasiyar (Tamil:மங்கையர்க்கரசியார்) was one of the 63 Nayanmars or holy Saivite saints who are revered in South India. She is one among the only three women who attained this distinction. Her devotion to Lord Shiva is recounted in the hagiographic poem Periyapuranam compiled by Sekkizhar as well as in the Tiruthondar Thogai written by the poet-saint Sundarar.
