Meaning & origin
Keagan is a modern given name adapted from an Irish surname, a trend that has been popular in the United States since the 1970s. Its first recorded use as a given name was in 1977, but it saw its peak in 2008. Since 2009, its popularity has been steadily declining, reflecting a broader shift away from certain Irish-derived names. In 2025, Keagan ranked 1609th with a frequency of 1 in 16,267 births. The name has seen the most use in states like Wisconsin, North Carolina, and Georgia, indicating a concentration in the Midwest and Southeast. While its exact meaning is debated, it is widely associated with 'little fire,' giving it a spirited feel. As a surname turned first name, Keagan fits a pattern seen with names like Riley and Logan, appealing to parents seeking a name with Irish heritage and a modern edge.
Keagan is an Anglicized form of the Irish surname Mac Aodhagáin, meaning 'son of Aodhagán', a diminutive of Aodh, the old Irish god of fire and sun. The name was traditionally a surname before being adopted as a given name in English-speaking countries from the 20th century onward.
