Armin is a German name best known from Arminius, the Germanic chieftain who defeated three Roman legions in the Teutoburg Forest in 9 AD; its meaning is uncertain and usually explained as "warrior" or "army man" from the Germanic heri. It is also a Persian name, borne by a hero of the Shahnameh, which is why it is common among Iranian and Bosnian families too. Armin has stayed just outside the top 2000 in the United States, peaking at number 1876 in 2023 and ranking number 2038 in 2025.
