Croix is the French word for "cross" and is pronounced "kroy" in American English. Parents usually know it from place names such as St. Croix in the US Virgin Islands or the St. Croix River between Wisconsin and Minnesota, which gives it an outdoorsy, Francophone flavor. The name hovers in the low 2000s: it reached number 1766 in 2019, its best rank, and stands at number 2334 among boys' names in 2025.
