Top Baby Names Starting with I

Along with Isabella and Isla, other girl names beginning with I in the US Top 600 include Ivy, Isabelle, Iris, Imani, and Itzel. As well as Isaac, other boy names starting with I in the US Top 600 include Isaiah, Ian, Ivan, Israel, and Iker.

Rare I names are easy to come by. International inspiration gives us the Dutch Ilse, Welsh Iago, and Arabic Inaya. Quirkier choices include retro nicknames Ike and Iggy, romantic Isabeau, and British favorite Imogen.
