Coursebooks as one of the learning sources are important to meet the students' needs, especially those that match with the current curriculum. The current curriculum in Indonesia is Merdeka Curriculum. Therefore, the value of Genre Based Approach (GBA) in the Merdeka curriculum in a 7th grade Junior High School English coursebook is examined. Adopted checklists, consisting of 25 items that focus on subjects and contents, skills and sub-skills, as well as practical considerations, are used as the evaluation matrix. The result answers three research questions. First, the coursebook shows a variety of activities. The most frequent reading activity is "read and answer questions", followed by "read and fill the blanks'' which becomes almost the two-fifth part from the whole reading activities. Next, "read descriptive text", "read sentences'', and "read comic strips'' also appear in the coursebook for less than 10%. The other reading activities are "read procedure text", "read and draw map", and "read a descriptive text and answer a true or false statement" (5.8% for each). Then, the last are "read and underline", "read and give checklist", and "read and ask someone's identity" with the smallest portion in the coursebook. Second, the genres that appear in the coursebook are descriptive, procedure, and persuasive text. Finally, the findings from the first and second research questions confirm that the analyzed coursebook aligns with the Genre-based Approach and adheres to the Merdeka curriculum standards.
