Meaning & origin

Acasia is a modern invented name that first appeared in U.S. birth records in 1989. It has never been common; its peak year was 2002, when it was given to a small number of baby girls. The name experienced a very slight rise in use beginning in 2022, suggesting a modest uptick in interest. Due to its rarity, it has no top states and is given across the country in very low numbers. Acasia is likely a creative respelling of Acacia, the name of a flowering tree, but its distinctive ending sets it apart. Its meaning is not historically rooted, making it a fresh choice for parents seeking a unique and melodic name.

Acasia is a modern coinage, first recorded in the United States in 1989. It appears to be a respelling or variant of Acacia, the botanical name for a genus of trees and shrubs, but with a distinct phonetic ending. The name may also be influenced by similar-sounding names like Alyssa or Cassia. Its use has been rare but slowly increasing since the early 2000s.
