This study aims to measure the impact of consumer animosity on product judgment, boycott motivation, boycott participation, and ethnocentrism among Indonesian consumers against Israeli products. This study is conducted in response to boycott declaration in the Organisation of Islamic Cooperation (OIC) Summit that was held in March 2016 in Indonesia. The objective of the boycott was to exert pressure on Israel over its invasion over Palestine. Data was collected through an online survey attracting 474 participants, but only 231 of them completed the questionnaire. Data was analysed using exploratory factor analysis and structural equation model. Results proffer that feelings of animosity significantly influence all predicted variables. Recommendation for future study is discussed.
