Meaning & origin

Macaulay is a rare given name in the United States, first recorded in 1990. Its usage saw a sharp spike around its peak year of 1992, coinciding with the actor Macaulay Culkin's stardom from the 'Home Alone' films (released 1990 and 1992). Despite the initial surge, the name has since settled into steady but modest use. As of 2025, it ranks 5,399, with approximately 1 in 100,475 boys receiving the name. The name has been gradually rising in popularity since 2001, though it remains uncommon. Macaulay is derived from a Scottish and Irish surname, giving it a strong Celtic heritage. Its trajectory suggests a niche but enduring appeal, particularly among parents drawn to names with a literary or historical feel.

Macaulay is a Scottish and Irish surname turned given name, derived from the Gaelic 'Mac Amhalghaidh', meaning 'son of the descendant of Amhalghaidh', a personal name of uncertain meaning. The name gained prominence as a given name in the United States after actor Macaulay Culkin rose to fame in the early 1990s. Despite its historical roots, modern usage is heavily influenced by popular culture.
