Purpose: This study aims to explore the role open data assumes in social innovation initiatives that combat the effects of Covid-19, in which quantitative information about these projects is complemented with the analysis of open data innovation capabilities.

Methodology: A mixed methods approach is adopted. Initially, quantitative data regarding the number of innovative projects is extracted from the OPSI framework. Then, in a second phase, qualitative data from each project is explored to explore the open data innovation capabilities offered by each initiative.

Results: The results reveal that most social innovation initiatives focus on the area of data visualization dashboards and open datasets. However, some projects address other areas, e.g. hackathons, service availability, and tourism information.

Implications: Covid-19 profoundly affects the lives of people and businesses, and open data can assume a determinant role in mitigating these effects and improve information transparency and collaboration between public and private entities.

Originality/Value: This study is relevant for the establishment of supportive public policies that promote the emergence of open-data-driven initiatives to mitigate the effects of Covid-19 in several areas such as the economy, education, and leisure.
