Lachey is a modern given name drawn from the surname, most widely recognized in North America through singer Nick Lachey. The surname itself carries several possible roots: it can derive from Irish Lahey/Leahy (Ó Laochdha), built on laoch “warrior, hero,” or reflect a Norman-French line related to Lacey, a habitational name from Lassy in Calvados. Some bearers trace it to French places such as Lachy (Marne), giving a straightforward “from Lachy” sense. Contemporary pronunciation in English is typically luh-SHAY.

As a first name, Lachey is rare and primarily 20th–21st century, fitting the surname-as-given-name trend. Usage remains modest and unisex, with a slight skew toward boys. Variants and cognates include Lahey, Leahy, Lacey, Lache, Laché, and Lachy; related feminized or respelled forms like Lacey sit alongside it in modern registries. Parents drawn to Lachey often appreciate its sleek sound and, under the Gaelic etymology, the heroic meaning.
