Roo

Roo—pronounced “roo”—feels like a little burst of sunshine in name form, one part playful kangaroo spirit, one part modern nickname chic. Though its roots stretch back through the Australian word for kangaroo and landed most memorably on the pages of A.A. Milne’s Hundred Acre Wood, today Roo stands on its own as a fresh, breezy choice for girls. It brings to mind an energetic heart, a boundless curiosity, and a story just waiting to unfold. In the United States, Roo has been bubbling under the radar—five newborns in 2020, eight in 2022, seven in 2023, and six in 2024—hovering around the 940s in popularity. That rarity only adds to its charm, making Roo a bright, inspirational pick for parents who want a name that hops happily ahead of the crowd.
