Amazon Disaster Relief is an internal Amazon corporate disaster-response initiative. It is not AmazonSmile, not a donor-advised fund, and not a separately incorporated Amazon foundation. Amazon uses its inventory, fulfillment centers, disaster-relief hubs, transportation network, cloud and communications technology, employees, and cash or product donations to support vetted humanitarian organizations before, during, and after disasters. Amazon describes sustained response activity beginning in 2017. The model is predominantly operational and in-kind. Relief hubs pre-position commonly requested items; response teams coordinate with nonprofit and public-sector partners; Amazon transports donated products from its inventory and wish lists; and AWS or technical teams may provide cloud, connectivity, mapping, and recovery support. Announced retail value, item counts, flights, truckloads, and logistics capacity are different from cash grants and should not be added together as a grant total. Amazon's current disaster-relief pages and 2026 response stories show active deployments, including relief shipments tied to floods, fires, earthquakes, and other emergencies. Partners—not the general public—typically identify priority goods and distribution needs. The public Disaster Relief by Amazon portal is a partner logistics mechanism, not a general grant application. No organization-wide open funding round, broadly applicable cheque size, or AUM exists for this internal initiative.
