SunHee Seo (Korean: 서선희; born in 1999 or 2000), known professionally as Ji-young Yoo (Korean: 유지영), is an American actress. She first appeared in the 2021 Netflix comedy-drama film Moxie, credited by her birth name. In the same year, she adopted the stage name Ji-Young Yoo, consisting of Korean syllables that she believed would be easier to pronounce for English speakers.

In 2023, Yoo won the Best Performance in a U.S. Narrative Feature accolade at the Tribeca Festival. She dropped out of her degree program at the University of Southern California to film the 2024 Amazon Prime Video original miniseries Expats, for which she earned an Outstanding Performance in a Limited Series nomination at the Gotham Awards. In 2025, she portrayed Megan, one of the main characters in Until Dawn, a horror film that takes place in the same universe as the 2015 video game of the same name. The film received generally mixed reviews, but various critics praised Yoo's character and performance.
