Jayne is a variant of the name Jane, which is of English origin. The name Jane itself is derived from the Old French name Jehanne, which in turn comes from the Latin name Iohanna, a feminine form of Iohannes. Iohannes is the Latin form of the Greek name Ιωαννης (Ioannes), which is derived from the Hebrew name יוֹחָנָן (Yochanan) meaning 'Yahweh is gracious'. Jayne, as a variant, carries the same meaning and is often used in English-speaking countries.
