Watching English videos with English subtitles can be used as one of the strategies to enhance vocabulary mastery. This study investigates how watching videos with English subtitles relates to students’ vocabulary mastery. The participants were 30 second-semester English language education students at UIN Ar-Raniry (2024 batch). Using a quantitative correlational design, the study used a Likert‐scale questionnaire and document (students final vocabulary and pronunciation scores0 as data collection.). The findings show that the average of students’ vocabulary scores was very good (M = 86.00, SD = 10.52), and for the questionnaire scores they had moderate‐high subtitle viewing (M = 51.20, SD = 11.43). However, Pearson’s correlation found a weak, non-significant link between viewing habits and vocabulary (r = .201, p = .286). While learners value subtitles for pronunciation and motivation, passive viewing alone did not boost vocabulary. Integrating active- learning strategies with subtitled videos and investigating factors like motivation or proficiency in experimental or longitudinal studies is recommended.
