Although physical activity enjoyment is associated with athletes’ psychological outcomes, the mechanisms underlying its relationship with mental well-being remain unclear. This study examined the mediating role of loneliness among athletes. A correlational survey design was employed. The participants consisted of 350 athletes selected through criterion sampling, including 178 females (Mage= 20.58 ± 1.99) and 172 males (Mage= 21.91 ± 4.88). Data were collected using the Physical Activity Enjoyment Scale, UCLA Loneliness Scale–Short Form, and Warwick-Edinburgh Mental Well-Being Scale. Pearson correlation analysis and PROCESS Macro Model 4 mediation analysis were conducted, and indirect effects were tested using 5,000 bootstrap samples. Physical activity enjoyment was positively associated with mental well-being (r= .586, p< .01) and negatively associated with loneliness (a= −.196, p< .01). Loneliness was negatively associated with mental well-being (b= −.447, p< .01). The mediation analysis revealed a significant indirect effect of physical activity enjoyment on mental well-being through loneliness (indirect effect= .088, 95% CI [.026, .147]). These findings indicate that enjoyment of physical activity contributes to athletes’ mental well-being and that loneliness partially explains this relationship. The results emphasize the importance of considering social connectedness and psychological experiences in understanding athletes’ well-being.
