Meaning & origin
Teagan is a modern adaptation of an Irish surname, rooted in the Gaelic name Tadhg. It first entered U.S. naming records in 1979, with a notable rise during the 2000s and peaking in 2016. Since 2017, its popularity has been gradually declining, falling to rank 340 in 2025, with about 1 in 1,798 baby girls receiving the name. The name has seen strongest adoption in states like South Dakota, North Dakota, and Maine. While historically masculine, Teagan has become predominantly feminine in contemporary American usage, reflecting broader trends of surname names crossing gender lines.
Teagan is an anglicized form of the Irish surname Ó Tadhgáin, which means 'descendant of Tadhgán'. The personal name Tadhgán is a diminutive of Tadhg, an old Irish name meaning 'poet' or 'philosopher'. The name gained popularity in the United States starting in the late 20th century, often used for girls, though it is unisex in origin. Its rise coincides with the trend for Irish surnames as first names.
