Although leisure provides numerous advantages, people sometimes feel guilty while engaging in leisure. The study objective was to explore the gender differences in the effects of socio-demographic factors and motivational factors on leisure guilt in Korea. Results showed that socio-demographic factors and leisure motivations influenced leisure guilt and the influence of these factors was different by gender. While age, number of children, and household income significantly influenced men's leisure guilt, only leisure expenditure did for women. When motivation was entered, only development and separation motivation were significant for men and adventure and relaxation motivation were significant for women.
