Meaning & origin

Mckinley originated as a Scottish and Irish surname before transitioning into a given name, a journey shared by many aristocratic surnames in the English-speaking world. In the United States, the name entered use as a masculine given name after the presidency of William McKinley, but by the late 20th century it had become almost entirely feminine. Reflecting its surname origins, Mckinley carries a strong, no-nonsense sound reinforced by the popular 'lee' suffix. The name reached its peak popularity in 2014, when it ranked highest among baby names, and has since been in decline, falling to rank 712 in 2025. Despite the downturn, it remains a distinctive choice that retains a unisex edge. Its modern usage largely mirrors the trend of using surnames as first names for girls, a pattern that continued through the 2010s. The name is most frequently chosen in Idaho, Oregon, and Mississippi, suggesting a geographic preference that aligns with its frontier surname feel. With roots stretching back to medieval Scotland and Ireland, Mckinley offers a link to Gaelic heritage and a sense of resilience.

Mckinley is an anglicized form of the Gaelic surname Mac Coinnle, meaning 'son of Coinneach.' Coinneach itself is a personal name derived from 'caoin' meaning 'fair, handsome' or 'comely.' The name arose as a surname in Ireland and Scotland and gained popularity as a given name in the United States in the late 20th century, notably after President William McKinley.
