This entry provides an introduction to the Stop Asian American and Pacific Islander Hate movement (Stop AAPI Hate), a US-based coalition with the objective of addressing and eradicating racism and discrimination against Asian Americans and Pacific Islanders. The inception of Stop AAPI Hate can be traced back to March 2020, a period coinciding with the height of the COVID-19 pandemic. Its formation was prompted by the urgent need to counter the alarming surge in anti-Asian hate incidents. Since the early stages of the global pandemic, Asian American and Pacific Islander (AAPI) communities found themselves unjustly targeted as scapegoats for the spread of the COVID-19 virus, resulting in a distressing increase in hate incidents and crimes against AAPI individuals. Consequently, a reporting center, known as Stop AAPI Hate has been jointly established by Chinese for Affirmative Action (CAA), AAPI Equity Alliance, and the Department of Asian American Studies at San Francisco State University. The primary objective of this reporting center is to systematically document reports of anti-AAPI violence and discrimination. This case study aims to explore the Stop AAPI Hate movement through the lens of social marketing perspective. The content of this case study draws from peer-reviewed journal publications, news clips, press releases, and research reports that have been meticulously documented by the reporting center established by Stop AAPI Hate.
