幽美 (yōu měi) is an elegant, literary adjective describing a quiet, refined kind of beauty — one that evokes tranquility, subtlety, and gentle charm. The character 幽 (yōu) conveys seclusion, depth, quietness, or mystery (as in 幽静 yōu jìng — 'serenely quiet'), while 美 (měi) means 'beautiful' or 'lovely'. Together, they emphasize beauty that is not showy or bold, but rather delicate, understated, and harmonious with nature or stillness.

This term is commonly used to describe natural scenery — misty mountains, secluded gardens, ancient temples nestled in bamboo groves, or quiet lakes at dawn — where silence and grace are central to the aesthetic impression. It appears frequently in classical poetry, travel writing, and descriptive prose, and carries a slightly formal, poetic register. While it can occasionally describe people or artistic works, its strongest associations are with serene, untouched natural or architectural environments.
