Macy comes from an English surname that goes back to Massy, a place in Normandy, and is usually explained as "Maccius's estate"; in the United States it is inseparable from the department store Macy's and its Thanksgiving parade. Singer Macy Gray helped make it a girls' name in the late 1990s. Macy ranked number 233 in 2000, peaked at number 219 in 2003 and has gradually declined to number 720 in 2025.
