This article examines the impact of informal intergovernmental relations on the Kenyan government's handling of the COVID-19 pandemic. It argues that although informality in governance has been perceived negatively by many governance scholars, it nevertheless has the capacity to enhance the effectiveness and legitimacy of government. By virtue of informality's adaptability and recognition of the centrality of context, it can enhance efficacy particularly in unpredictable circumstances as occurred in the pandemic. Notwithstanding this reality, until recently, literature on informality, mainly informed by Eurocentric colonial perspectives on governance, has focussed on its negative elements, criticizing it for diverse governance ailments. Through the prism of the negotiated order theory, this article challenges this dominant narrative using an analysis of informal intergovernmental relations during the COVID-19 pandemic in Kenya. It argues that though informality was at times applied negatively, overall, it ensured vibrant intergovernmental relations, thus positively impacting health service delivery and enhancing the government's legitimacy in the management of the pandemic.
