Meaning & origin
Koah is a modern American name that first entered the U.S. Social Security records in 2005. As of 2025, it ranks 912th among boys, with approximately 1 in 6,570 newborns receiving the name. Its popularity has been rising steadily since 2006, reaching a peak in 2025. The name is most common in Louisiana, Oklahoma, and South Carolina. Koah exemplifies the trend of inventing new names from phonetic building blocks, and its trajectory suggests it may continue to gain familiarity without becoming ubiquitous.
Koah is a modern American coinage, likely formed from the popular K- sound and the fashionable -oah ending reminiscent of names like Noah or Jonah. It first appeared in U.S. birth records in 2005 and has since gained steady use. The name does not have a traditional etymology or historical lineage beyond its contemporary creation.
