Meaning & origin
Rheagan is a modern, feminine name that emerged in the early 1980s, first recorded in 1980. It reached its peak popularity in 2004, reflecting the trend of spelling variations on traditional Irish surnames. As of 2025, it is a rare choice, with approximately 1 in 229,610 girls receiving the name that year, and its usage has been declining since 2004. The name is a variant of Reagan, which itself saw a surge in the 1980s due to President Ronald Reagan. Rheagan remains uncommon, appealing to parents seeking a distinctive yet familiar-sounding name with Irish roots. It has not been recorded among the top baby names in any specific U.S. state, indicating its scattered, niche appeal.
Rheagan is a modern spelling variant of the Irish surname Reagan or Regan, which derives from the Gaelic Ó Riagáin, meaning 'descendant of Riagán.' Riagán itself is a diminutive of rí, meaning 'king,' so the name carries connotations of royalty. The name entered use as a given name in the late 20th century, influenced by the popularity of similar-sounding names like Reagan and Megan.
