Opal
Girl name · #423 in 2025 · Distinctive
Opal is currently the #423 girl name in the United States — 740 babies received it in 2025. A decade ago it stood at #1110, so the name has been rising over the past ten years. Roughly one in every 2,432 girls born in 2025 was named Opal.
The 145-year story
Opal first appears in the Social Security records in 1880, when 5 girls received the name. Its peak came in 1918, when 2,847 girls were named Opal — good for #94 that year. Today's parents encounter it as a name from their grandparents’ generation, which is precisely the vintage window from which names get revived. Following the curve matters more than today's snapshot: a name's position on its rise-peak-decline arc is the best predictor of how common it will feel in a kindergarten class five years from now.
