Meaning & origin

Reagen is a modern first name that emerged as a feminine variant of the surname Reagan, drawing on the Irish Ó Riagáin, which may mean 'little king.' It first appeared in U.S. birth records in 1974 and saw its peak popularity in 2011, likely reflecting the broader trend of surname names and the Reagan political legacy. Since 2012, its usage has been declining. The name has never broken into the top 1000 nationally, and its highest ranks were in the late 2000s and early 2010s. While unisex, it is most often given to girls, with spellings like Reagan and Raegan also common. The name has no strong regional ties, as it does not appear as a top name in any U.S. state.

Reagen is a modern given name, typically a variant of the surname Reagan. The surname Reagan is an Anglicized form of the Irish Ó Riagáin, meaning 'descendant of Riagán.' Riagán is a personal name of uncertain origin, possibly derived from the Irish word rí meaning 'king' combined with a diminutive suffix, thus 'little king.' The name rose to prominence in the late 20th century, likely due to U.S. President Ronald Reagan, and is often chosen for girls, though it remains unisex.
