Ji-soo is Korean in Origin.

Ji-soo (지수) is a Korean unisex given name formed from Sino-Korean elements ji and su. Its sense depends on the hanja chosen; South Korea authorizes dozens for each syllable. Popular pairings include 智秀 “wisdom and excellence,” 志守 “will and protection,” and 知粹 “knowledge and purity,” though many other combinations are possible. Pronounced roughly “jee-soo,” it appears in Romanization as Ji-su, Ji-soo, or Jisoo, with the hyphen optional; older systems sometimes yield Chisu.

Sino-Korean given names have dominated Korean naming since the Joseon era, and Ji-soo gained wide use in the late twentieth century. It remains familiar across generations and today skews slightly feminine in South Korea while still used for boys. Global visibility rose through public figures such as BLACKPINK’s Jisoo and the actor Ji Soo. The name’s versatile structure and virtue-leaning meanings make it a stylish, adaptable choice in Korea and the diaspora.
