This study was conducted to examine the relationship between social media usage and happiness levels of individuals who do fitness exercises for recreational purposes. The population of the research consisted of adult individuals who are members of fitness centers in Mersin province and districts in 2023. The sample of the research consisted of a total of 566 participants, 190 women and 457 men, who were members of fitness centers in Mersin province and districts in 2023. "Personal information form", "Oxford Happiness Scale Short Form" and "Social Media Usage Scale" developed by the researchers were used as data collection tools. In comparing the scores obtained from the scales according to categorical variables, independent samples t test was used for categorical variables containing two groups, and analysis of variance was used for categorical variables containing three or more groups. As a result of the variance analysis, the Tukey test, one of the multiple comparison tests, was used to determine the difference between the groups. The relationships between the subdimensions of the scales were examined with Pearson correlation analysis. Analyzes were carried out with the help of SPSS program. As a result of the analysis, it was determined that there was a statistically significant positive relationship between continuity and competence, which are sub-dimensions of the participants' social media use scale. As a result, it was determined that the continuity sub-dimension and competence sub-dimension scores of the participants' social media usage were at medium levels, and the happiness scale scores were high. As the continuity of social media use of the participants increased, their happiness scores decreased, and as the social media usage competence score increased, their happiness scores increased.
