Humberto is the Spanish and Portuguese form of Humbert, a Germanic name from hun, "warrior" or "bear cub", and beraht, "bright", so it is usually read as "bright warrior". It has been a steady favorite in Mexico and among Mexican American families, often shortened to Beto. Humberto ranked number 575 in 2000, peaked at number 565 in 2001 and has declined gradually to number 1876 in 2025, with 84 boys given the name.
