Meaning & origin
Lennox began as a Scottish surname and place name, but in the United States it has gained traction as a first name relatively recently. The name first appeared in U.S. records in 1918, though it remained rare for decades. Starting in 1986, the name began a steady upward trajectory that continues today. Its peak year so far was 2022, when it reached its highest rank. As of 2025, Lennox stands at rank 289, with about 1 in 1472 newborns receiving the name. The name is most popular in states like Iowa, Louisiana, and Mississippi, indicating a concentration in the South and Midwest. Its rise likely reflects the trend toward surname names and names ending in 'x', similar to Knox and Jax. Lennox remains unisex but is still more common for boys.
Lennox is a Scottish surname turned given name, originally a place name referring to the district of Lennox in the historic county of Dunbartonshire. The name is generally believed to derive from the Gaelic 'leamhan' (elm) combined with a locative suffix, thus 'place of elm trees'. It gained popularity as a first name in the late 20th century, especially for boys, though it is increasingly used for girls as well.
