Agnes of Rome [born c291] is a virgin martyr, venerated as a saint in the Roman Catholic Church, Eastern Orthodox Church, the Anglican Communion, and Lutheranism.
She is one of seven women who, along with the Blessed Virgin, are commemorated by name in the Canon of the Mass.
Agnes is depicted in art with a lamb, evoking her name which is based on the Latin word for "lamb", agnus (the given name is Greek, from hagnē ἁγνή "chaste, pure"). She is also shown with a martyr's palm.
She is the patron saint of chastity and virgins.
Agnes' feast day is 21 January.
In pre-1970 versions of the General Roman Calendar an additional feast of the same saint is given one week later, on 28 January (see Tridentine Calendar). The 1969 revision removed this as a duplication of the 21 January feast.
Saint Agnes was executed 306 Anno Domini.
