This research is motivated by the low level of students’ interest in learning Arabic, which is often perceived as difficult and less engaging. Therefore, this study aims to: (1) identify how the TikTok application is used in Arabic language learning for fourth-grade students at SD IT Generasi Madani Sampali; (2) determine the level of students’ interest in learning Arabic; and (3) examine whether the use of the TikTok application influences students’ interest in learning Arabic in grade IV at SD IT Generasi Madani Sampali.This study employed a quantitative research design. The data sources consisted of primary and secondary data. The population of this study was 30 students, and a saturated sampling technique was applied. Data were collected through questionnaires and documentation. The data analysis techniques included: (1) descriptive statistical analysis; (2) instrument testing, consisting of validity and reliability tests; (3) prerequisite tests, namely normality and linearity tests; and (4) hypothesis testing using simple linear regression, partial tests (t-test), and the coefficient of determination.The results showed that the partial t-test produced a significance value of 0.00, which is less than 0.05. This indicates that H₀ is rejected and Hₐ is accepted, meaning that the use of the TikTok application has a significant effect on students’ interest in learning Arabic for fourth-grade students at SD IT Generasi Madani Sampali. The magnitude of the influence of the TikTok application on students’ interest in learning Arabic was 50%, while the remaining 50% was influenced by other factors not examined in this study.
