The Discalced Carmelites, known officially as the Order of the Discalced Carmelites of the Blessed Virgin Mary of Mount Carmel () or the Order of Discalced Carmelites (; abbrev.: OCD), is a Catholic mendicant order with roots in the eremitic tradition of the Desert Fathers and Mothers. The order was established in the 16th century, pursuant to the reform of the Carmelite Order by two Spanish saints, Saint Teresa of Ávila (foundress) and Saint John of the Cross (co-founder). "Discalced" is derived from Latin, meaning "without shoes".
