This study aimed to assess the correlation between political ideologies, government trust, and COVID-19 vaccine hesitancy in South Korea during the COVID-19 pandemic. A cross-sectional survey was conducted among South Korea’s general population and 1000 respondents (aged 18 years and older) were included. We used multivariate logistic regression models to identify the factors associated with vaccine hesitancy. Respondents who self-identified as liberal or held “no political opinion” had higher rates of vaccine hesitancy than conservative respondents. People’s trust in the government’s countermeasures was associated with vaccination. Respondents who had risk perceptions (affective and cognitive) of COVID-19 had lower rates of vaccine hesitancy. Perceptions that the vaccine was not safe and being aged 18–29, 30–39, or 40–49 were associated with a higher probability of vaccine hesitancy. This study found that even if vaccine safety and risk perceptions toward COVID-19 were adjusted, self-rated political ideologies and government trust was associated with COVID-19 vaccine hesitancy. More effort to communicate with those who are *liberal or “no political opinion”, younger, and have lower level of trust in the government are required to dissolve vaccine hesitancy. Further studies should analyze the mechanism of COVID-19 vaccine uptake for effective herd immunity.
