勇猛 (yǒng měng) is an adjective meaning 'fierce and brave' — combining 勇 (yǒng), which conveys courage, boldness, or heroism, and 猛 (měng), which adds intensity, ferocity, or sudden force. Together, they describe someone or something that acts with both fearless determination and powerful energy. It emphasizes not just bravery in the face of danger, but also the vigor and aggression needed to overcome strong opposition.

This word is commonly used to describe animals known for strength and fearlessness — such as lions, tigers, eagles, or mythical creatures like dragons — and appears frequently in martial arts contexts, historical narratives, and descriptive writing about warriors or heroic figures. While it can describe people, it tends to carry a slightly literary or elevated tone, and is rarely used in casual speech about ordinary individuals.
