Neilan is an infrequently used Irish-derived name that has seen modest but declining usage since its peak year of 2017, when it ranked 9,714th. At that time, approximately 1 in 244,011 boys were named Neilan. The name has never appeared in top state rankings, reflecting its rarity. Its trajectory has been falling since 2017, indicating a downturn in recent years. First recorded in 1922, Neilan has maintained a low but persistent presence in American naming, likely appealing to families seeking an alternative to more common Irish names like Neil or Niall.

Neilan is an Anglicized form of the Irish surname Ó Néill, meaning 'descendant of Niall'.
