State Disaster Mitigation Fund is a fund established by State Governments, often with contributions from the Central Government, to finance projects and initiatives aimed at reducing disaster risks, such as strengthening infrastructure, promoting awareness, and implementing long-term resilience measures to minimize the impact of future disasters. The fund supports projects not covered by regular government schemes and focuses on structural and non-structural measures to build communities and infrastructure that can withstand potential hazards. 

States are legally required to set up SDMF after establishing their State Disaster Management Authority, as mandated by the National Disaster Management Act, 2005. 

It is supported by both the central government (in a ratio of 75:25 for most states, 90:10 for NE&H states) and the state government
