Ascent of Mount Carmel (Subida del Monte Carmelo) is a 16th-century spiritual treatise by Spanish Catholic mystic and poet St John of the Cross. The book is a systematic treatment of the ascetical life in pursuit of mystical union with Christ, giving advice and reporting on his own experience.

It is part of four works by John dealing with the so-called Dark Night of the Soul, when the individual Soul undergoes earthly and spiritual privations in search of union with God. Along with the other three, The Dark Night Of the Soul, The Living Flame of God and the Spiritual Canticle, it is regarded as one of the greatest works of mysticism in Christianity and in the Spanish language.
