Collective narcissists are hostile towards outgroup members, especially in response to threats against the ingroup. In the current study ( N = 662; Polish community sample), we examined the associations between collective narcissism and intergroup relations using the agency–communion model of collective narcissism during the initial weeks of the COVID-19 threat in Poland. Assuming the COVID-19 threat is agentic (i.e., related to biological and economic danger), we expected it to be unrelated to collective narcissism’s communal aspect. We also expected that collective narcissists would enhance their ingroup image to modify the effects of the COVID-19 threat on intergroup relations. In general, collective narcissism was related to less favorable attitudes toward the European Union, more favorable attitudes toward China, and a willingness to help Italians. The agentic aspect of narcissism was unrelated to intergroup prosocialness, while the communal aspect of narcissism was unrelated to attitudes toward the European Union. The COVID threat suppressed unfavorable attitudes towards the European Union among collective narcissists. Therefore, the COVID threat has limited yet unexpected effects on attitudes toward outgroups among collective narcissists.
