Zosimas of Palestine (Greek: Ζωσιμᾶς; Arabic: زوسيماس الفلسطيني, romanized: Zōsīmas al-Falesṭīnī), is commemorated as a Palestinian saint.

He became a monk in a monastery in Palestine at a very young age, gaining a reputation as a great elder and ascetic.

At the age of fifty-three, now a hieromonk, he moved to a very strict monastery located in the wilderness close to the Jordan River, where he spent the remainder of his life.

It was the custom of that monastery for all of the brethren to go out into the desert for the forty days of Great Lent,[3] spending the time in fasting and prayer, and not returning until Palm Sunday.

[4] All that is known of Zosimas' life comes from the Vita of St. Mary of Egypt,[5] recorded by Sophronius, who was the Patriarch of Jerusalem from 634 to 638.
