Wonyoungism, also referred to as #Wonyoungism or the Wonyoung effect, is a trend on social media among some K-pop fans based around former Iz*One member and current Ive member Jang Won-young, also known mononymously as Wonyoung. Despite its name, Wonyoungism has not been addressed or acknowledged by Jang herself and is entirely propagated by her fans.

Some supporters of Wonyoungism describe it as a source of self-motivation, self-care, and an expression of the coquette aesthetic. Critics argue that it encourages eating disorders by fostering low self-esteem, unhealthy body image, perfectionism, and other harmful lifestyle habits. They also contend that it unfairly damages Jang's reputation by linking such behaviors to her.
