The impact of COVID-19 on our way of life is yet to be fully understood. However, social psychology theory and research offer insights into its effect on social attitudes and behaviors, and here we gather the views of a unique group of experts in group processes and intergroup relations. Group processes and intergroup relations are major factors in social resilience and change arising from the COVID-19 pandemic. This special issue was developed to foreground the crucial role of group processes and intergroup relations in the COVID-19 pandemic. This article provides an overview of the areas explored in the special issue. First, we focus on the impact on societies, covering the evolution of intergroup processes during the pandemic, leadership, social connectedness, cultural differences in responses, and social development. Second, we turn to intergroup inequality and focus on gender inequality, ageism, xenophobia, and racial bias during COVID-19. Third, we explore worldviews during the pandemic, specifically conspiracy theories, science skepticism, and existential threat. Finally, we focus on the pandemic’s impact on behaviors, covering virtual working, social activism, virtual ostracism, and conformity and deviance. We finish with a discussion of the value of social psychology in helping us understand the impact of COVID-19 on social attitudes and behavior. As this special issue shows, group processes and intergroup relations are central to the ways that individuals and society is dealing with the challenges of this pandemic.
