Meaning & origin

Gregor is a name with a long and steady, if uncommon, presence in the United States. It first appeared on U.S. birth records in 1897, the same year it reached its peak rank of 8,243, when it was given to a relative handful of newborn boys. As of 2025, the name remains rare, with about 1 in every 189,786 male births receiving it. Its trajectory has been falling since 2005, reflecting a broader shift away from traditional classic names in favor of more modern or revived choices. While Gregor has never been among the top baby names in any state, its enduring use speaks to its cross-cultural appeal: it is the standard form of Gregory in Scotland and across much of continental Europe, bearing the same ancient Greek root meaning 'watchful.' This legacy gives Gregor a quiet, scholarly dignity, reinforced by its association with Gregor Mendel, the 19th-century scientist whose work in genetics reshaped biology. For parents seeking a name that is both familiar and distinctive, Gregor offers a polished, understated alternative to the more common Gregory.

Gregor is the Scottish form of Gregory, derived from the Latin Gregorius, which itself comes from the Greek Gregorios, meaning "watchful" or "vigilant." The name has been used in Scotland since the Middle Ages, notably by the Clan Gregor, and saw limited but consistent use in the United States. Its popularity peaked early in the 20th century, likely bolstered by the fame of Gregor Mendel, the father of genetics.
