Jordyn is a feminine spelling of Jordan, the name of the river in which Jesus was baptized; it comes from the Hebrew yarden and means "to flow down" or "descend". The spelling with a y became a popular way to mark the name as a girl's name in the 1990s. Jordyn peaked at number 112 in the United States in 2010 and has since eased to number 371 in 2025.
