Reighan is Irish in Origin.

Reighan is a modern, stylized variant of Reagan/Regan, an Irish surname‑turned‑given name from the Gaelic Ó Riagáin “descendant of Riagán.” The personal name Riagán has debated roots: it is widely glossed as “little king,” connecting rí “king” with the diminutive ‑án, though some scholars relate it to riag/riagach, “impetuous” or “vigorous.” The Shakespearean character Regan in King Lear gave the form early literary visibility, while the surname’s prominence in the 20th century - especially through U.S. President Ronald Reagan - propelled its adoption as a given name.

Reighan follows the contemporary -eigh spelling trend seen in names like Ryleigh and Ashleigh, and is used as a unisex choice, though it skews feminine in North America. Common variants include Reagan, Regan, Raegan, Ragan, Raygan, Reaghan, and Reegan; short forms such as Rae or Ray also appear. Usage rose sharply from the 1980s onward and remains steady in many English‑speaking countries.
