Chulsoo is Korean in Origin.

Chulsoo (철수) is a Korean masculine given name formed from Sino-Korean elements; in Revised Romanization it is Cheol-su, with variant spellings Chul-soo, Cheol-soo, Chul-su, and North Korean Chol-su. Meaning varies by hanja: 철 may be 哲 “wise; philosophical” or 鐵 “iron; steadfast,” while 수 can be 秀 “outstanding,” 守 “to guard,” 洙/洲 “islet/river,” or 壽 “long life.” Popular pairings include 哲秀 (“wise and excellent”) and 鐵守 (“iron-strong protector”), among many other combinations officially permitted for names in Korea.

The name rose to prominence in mid-20th-century Korea, becoming the archetypal boy’s name in schoolbooks - comparable to “John” in English - before declining as trends shifted toward modern or native-Korean names. It now conveys a classic, approachable everyman image. Notable bearers include entrepreneur–politician Ahn Cheol-soo and film director Park Cheol-su. Parents choosing Chulsoo often aim to evoke intelligence, resilience, and merit.
