Meaning & origin
Jacy entered U.S. birth records in 1961, and since then it has remained a relatively uncommon choice. Its highest point was in 1992, when it peaked in usage before gradually declining. Since 2001, the name has followed a downward trajectory, with its most recent rank of 7,491 in 2025 reflecting its current rarity. Jacy's appeal likely lies in its simple, melodic sound and its resemblance to more popular names like Casey and Macy. Despite its low frequency of use, it continues to be chosen by a small number of parents each year for their daughters.
Jacy first appeared as a given name in the United States in the early 1960s. It is often considered a modern invented name, possibly arising as a respelling of Casey or as a feminine form of Jace. Its rise in popularity during the 1990s suggests it was influenced by trend for names ending in the 'ee' sound.
