Sang is an uncommon unisex given name of Vietnamese origin, meaning 'increase' or 'prosperity'. It's composed of two Chinese characters: 上 (shàng) meaning 'above' and 生 (shēng) meaning 'life' or 'birth'. In Vietnamese culture, Sang is often used as a middle name, but it can also be used independently. The name gained popularity in the West through its association with notable figures like Sang Nguyen, a Vietnamese-American chess grandmaster.
