Deegan

This name shares sounds with Keagan and Teagan, but has its own roots in Irish culture. It comes from the surname O'Duibhginn, meaning "descendent of the dark-haired one". Freestyle Motocross rider Brian Deegan may be partly responsible for this name's appearance in the US Top 1000 between 2008 and 2013. While it is now out of the charts, it remains a familiar choice, given to just shy of 100 boys in a recent year.

Deegan is also given to girls.

Pronounced DEE-gun.

As of October 2026, Deegan ranked #13256 in US births in 2016 SSA.
