Meaning & origin

Madai is a rare given name in the United States, first recorded in 1979. Its peak year, 2009, saw the most births, but the name has been falling in use since 2002. Despite a biblical origin as the name of a son of Japheth in Genesis, Madai today is nearly exclusively given to girls, suggesting it functions as a modern coinage or a phonetic variant of names like Madi or Maya. The name has never broken into the top 1000 rankings, so it remains a highly uncommon choice. No top states are associated with its use, indicating it is scattered across the country. Its trajectory shows a sustained decline, though the latest recorded year is 2025, indicating continued but sparse usage.

Madai appears in the Bible as the name of a son of Japheth, but as a given name in modern usage it is likely a creative spelling or a revival. Its use as a feminine name in the US since 1979 suggests it may have been independently coined, possibly influenced by names like Maya or Madi.
