Reagan, an Irish surname-turned-given-name, comes from the Irish name Riagán, which is derived from the Old Irish elements rí, meaning "king," combined with a suffix. Some people translate it to mean "little king" or "the King's child," giving this name a regal feel. Reagan first appeared on the Social Security Administration's top 1,000 for girl names in 1975 and has been a top-200 girl's name every year since 2004 (including four years inside the top-100). It's the name UFC champion Amanda Nunes gave her daughter Reagan Ann, born in 2020, and can be a great way to honor former President Ronald Reagan.
