What does the name Sierra mean?

Sierra is a Spanish word name. In Spanish, sierra means a saw and, from the jagged look of a saw blade, a range of mountains; the Real Academia Española and the American Heritage Dictionary both trace it to Latin serra, saw. English borrowed the word for a rugged mountain range with a jagged outline. Wiktionary describes Sierra as a modern American girls' name from the Spanish noun, sometimes confused with the similar-sounding Ciara and Sarah.
