Meaning & origin

Rhegan is a modern respelling of Reagan that first appeared in U.S. records in 1994. The name saw its peak popularity in 2004, when it ranked among the highest in usage. As of 2025, it has been on a rising trajectory since 2019, though it remains relatively rare, with about 1 in 178,585 newborns receiving the name in the latest year. The spelling Rhegan offers a distinctive twist on the traditional Irish surname while maintaining its familiar sound. Most common in the United States, the name has not been heavily concentrated in any single state, reflecting its broad but sparse use across the country.

Rhegan is a modern respelling of Reagan, an Irish surname derived from Ó Riagáin, meaning "descendant of Riagán." Riagán itself is a personal name of uncertain origin, possibly meaning "little king" from Irish rí "king" combined with a diminutive suffix. The name Reagan gained popularity in the late 20th century, and Rhegan emerged as a phonetic variant primarily used for girls, first recorded in U.S. data in 1994.
