The name Heidi is a girl's name of German origin meaning "of noble birth". Heidi is ranked #363 on our popularity charts and is often added to lists like Baby Names from Children's Books and discussed in our forums with posts like "How many ____s do you know?".
From the experts:
Heidi became known—and popular—via the 1880 eponymous children's classic by Swiss writer Johanna Spyri and, despite decades of American Heidis of all sizes, shapes, and personalities, the name seems permanently tethered to that spunky little girl on the Alpine mountaintop in the book and Shirley Temple movie.
The movie was released in 1937, and two years later the name popped onto the charts, and would, a few decades later, be a Top 100 name for close to twenty years. The prominence of Heidi Klum on Project Runway has given it a new recent bump.
