The boycott of products affiliated with Israel is a global phenomenon that is ongoing in various countries, including Indonesia. Consumers carry out boycotts as a form of support for Palestinians and as protests against Israel's actions. This study analysed the influence of religiosity, social media, animosity, and consumer ethnocentrism on boycott behaviour and switching behaviour toward products affiliated with Israel. The research used a quantitative approach, with 286 respondents. This research used non-probability sampling techniques, including voluntary sampling, and analysed the data using descriptive and SEM methods. Results showed that religiosity did not affect animosity, whereas social media affected animosity. Religiosity, social media, animosity, and consumer ethnocentrism significantly affect boycott behaviour. Boycott behaviour and animosity significantly affected switching behaviour. However, religiosity did not affect switching behaviour.
