The COVID‐19 pandemic has been one of the most significant public health events in human history. Domestic violence cases surged globally during the COVID‐19 pandemic. In Taiwan, this trend was particularly evident, with a year‐over‐year increase in reported cases. This study aims to investigate the complex dynamics of domestic violence in Taiwan during the COVID‐19 pandemic through the lens of Complexity Theory. The researcher employed a qualitative case study method and conducted semistructured interviews with four participants. A cross‐case analysis revealed four themes illustrating polymorphic correlations of factors and five themes related to self‐organizing behaviors. This study amplifies the voices of domestic violence victims during the COVID‐19 pandemic and offers insights into the intricate dynamics between domestic violence incidents and disasters, individuals, and systems. Implications for theory and practice are discussed.
