Jayne is a spelling variant of Jane, the English feminine form of John, and means "God is gracious". Hollywood star Jayne Mansfield popularized this spelling in the 1950s, and Jayne Torvill made it famous on the ice in the 1980s. In the United States it has never been common: number 1782 in 2000, its best recent year, and number 2837 in 2025.
