Meaning & origin
Heidy is a spelling variant of Heidi, a name that rose to prominence through children's literature. In the U.S., Heidy was first recorded in 1955, and its popularity peaked in 2010. Since 2009, its usage has been declining. In 2025, the name ranked 1,911th with a frequency of 1 in 15,914 births. The name is most common in New York, Georgia, and California. While connected to the well-known Heidi, the Heidy variant offers a slightly more distinctive spelling that has maintained modest but steady usage over decades.
Heidy is primarily a spelling variant of Heidi, a German diminutive of Adelheid, which derives from the Old High German elements 'adal' (noble) and 'heit' (kind, sort). Heidi gained international recognition through Johanna Spyri's 1880 novel 'Heidi'. The variant Heidy may also be influenced by Scandinavian names beginning with 'Heid-', such as Heidrun from Old Norse 'heiðr' (heath) and 'rún' (secret lore).
