Darien is a baby boy name with Irish, Gaelic, and British origins. Branching off of its Gaelic roots, Darien, closely connected to Darragh and Daire, means “oak tree.” While this name is already so grand in stature, Darien is also associated with the name Darren, which means “great” in Irish and “small, rocky hill” in English. Whether baby grows as tall as a majestic tree or has the biggest heart, a name like Darien can be one magnificent pick.
