Diogo

Diogo is the much-less-known brother of Diego, both forms of James, which is itself a form of the Biblical Jacob. And Diego itself probably started life as a short form of Santiago, aka Saint Jago, aka Saint James.

That's a lot of variations for one name. In Diogo's case, Americans will forever mistake it for Diego, which was used for nearly 3000 baby boys in the US last year, while Diogo was given to fewer than five.

Pronounced dee-AH-go.

As of October 2026, Diogo ranked #7807 in US births in 2025 SSA, peaked at #1842 in 2004.
