This study aims to investigate the relationship between the reading motivation and reading comprehension self-efficacy perceptions of fourth-grade students. The research model is the correlational survey model, one of the quantitative research methods. The study group of the research consists of 571 students studying in the fourth grade. The 'Reading Motivation Scale' and the 'Reading Comprehension Self-efficacy Perception Scale' were used as data collection tools. The SPSS statistical software program was used for the analysis of the data. Independent Samples T-Test and ANOVA, which are parametric tests, were used in the analysis of the data. When the results obtained in the study were examined, it was seen that the students' reading motivation total scores were at a 'good' level, and that there was no significant difference in their total scores according to the gender and Turkish report card grade variables. Similarly, it was concluded that the students' reading comprehension self-efficacy perception total scores were also at a 'good' level, and that there was no difference between students depending on the gender and Turkish report card grade variables. Finally, it was determined that there was a 'moderate' positive relationship between the students' reading motivations and their reading comprehension self-efficacy perceptions.
