Macey is a spelling of Macy, an English surname that goes back to the Norman French place name Massy, which in turn comes from the Latin personal name Maccius; as a first name it is usually glossed as "weapon" by association with the mace, though the link is folk etymology. The department store Macy's made the name feel familiar and upbeat. Macey peaked at number 494 in the United States in 2001 and ranks at number 1619 in 2025.
