This research is motivated by the low mathematical literacy skill of Indonesian students and the existence of Instagram as one of the online learning media during the pandemic. The purpose of this research is to describe the use of Instagram to facilitate mathematical literacy for 85 grade VIII students at a private junior high school in Jakarta and to find out the subjects' responses to the use of Instagram. Data were gathered by Instagram media analysis and questionnaire distribution. Data were analyzed by descriptive and qualitative methods. The results of this study showed that Instagram was used as a medium for evaluating mathematical literacy. Instagram was used limitedly to display mathematical literacy problems with the scope of mathematics material for middle school grade VIII. Researchers used Instagram feeds to introduce the context of the literacy problems to students, show the question, and display the discussion and solution. The questionnaire responses showed that the subjects agreed to the use of illustrations in Instagram because it helps in understanding the questions and adds to the attractiveness. The subjects suggested simplifying the solutions and the using of video to explain the solutions would be more effective and easier to understand. Because of the limited use of Instagram, the influence of Instagram on literacy skills has not been explored further.
