The present study investigates the relationship between self-regulation, self-esteem, attitude and foreign language achievement (FLA). The research was conducted with 383 students from Gaziantep University Higher School of Foreign Languages. The data were collected through a modified questionnaire adapted from three different questionnaires. The statistical results showed that there was a positive relationship between self-regulation and foreign language achievement (r= .319 p >.01), self-esteem and foreign language achievement (r= .404 p >.01), and attitude and foreign language achievement (r=.425 p >.01). Moreover, when self-regulation, self-esteem and attitude came together, a statistically significant positive relationship with foreign language success was observed (r= .540 p >.01). Self-regulation, self-esteem and attitude in relation to academic success have been analyzed together for the first time in this study.
