This study aims to determine the best science literacy-based physics textbook. This research is a descriptive study with data analysis techniques using the weight product method as a decision support system. The research sample comprised eleven high school physics textbooks for class X in Lampung Province. Methods of collecting data through observation, interviews, documentation, and questionnaires. Based on the research, the selection of the best science literacy-based physics textbook is made using the weight product method with the following steps: determining the criteria, making a suitability rating between alternatives and criteria, determining the weight of each criterion and its normalization, calculating the S value as an alternative preference, calculating the V value as a final alternative preference for ranking. Based on the final calculation results, the best alternative high school physics textbook based on science literacy was obtained with a value of V = 0.1070, namely B11.
