Deir ʿAsfīn (Arabic: {{linktext|دير, "Convent of Deviation") was a former monastery in Ottoman Palestine located just north of Tira in present-day Israel. It appeared on Sheet XI of the 19th-century Survey of Western Palestine and its peak formed the highest point of the Falik Hills in the maritime plains south of Mount Carmel, with an elevation of 302feet above sea level. It has also been identified as the location of the Theraspis (Greek, Ancient (to 1453);: Θερασπις) that appears on the Madaba Map of 6th-century Byzantine Palestine.
