Meaning & origin

Tully is a rare unisex name drawn from an Irish surname. It first appeared in U.S. records in 1900, when it was most popular, ranking 6,143rd overall with a 1-in-122,005 birth rate in the latest year 2025. The name has been in steady decline since 2022, though it has never been common. Its brevity and strong sound give it a modern feel despite its old roots.

Tully is an anglicized form of the Irish surname Ó Taithligh or Mac Taithligh, derived from the Gaelic word 'taithleach' meaning 'quiet' or 'peaceful'. Alternatively, it may come from the Irish word 'tuile' meaning 'flood'. As a given name, it emerged in the late 19th and early 20th centuries, particularly in the United States, but has remained rare.
