This study aims to assess the level of academic procrastination among Turkish EFL learners, and how it varies depending on their proficiency level of Turkish EFL learners. It attempts to explore the relationship between procrastination, self-esteem, self-efficacy and self-regulation among Turkish EFL learners. This research was conducted among students enrolled in a preparatory program at a state university in Turkey who were attempting to acquire English. There were 202 participants in total, with 64 females and 138 males. The participants were given a 44-item questionnaire to complete. There were three levels of proficiency involved in the study: A2, B1, and B1+. The participants are between the ages of 18 and 26. The findings revealed that Turkish EFL students had a moderate level of procrastination. There are no differences between the responses of the participants based on their English level. Procrastination was significantly negatively correlated with self-esteem, self-efficacy, and self-regulation.
