There are many relief organizations that need donations to help those affected by the disaster.

The American Red Cross is a volunteer-led humanitarian organization that provides relief to disaster victims. The organization acts under the guidance of the Fundamental Principles of the International Red Cross and Red Crescent Movement. Donations help to provide relief mobilization of emergency personnel, vehicles, shelter and supplies to those affected.

Another organization is Americares, which helps bring medical aid supplies around the world. The global relief organization focuses on responding to medical emergencies and providing medicine to those affected by disasters. A donation will go toward providing emergency kits to families. As a global humanitarian organization, Americares delivers aid to all who need it no matter where they are. 

The Salvation Army National Corps responds to long-term disasters for support in the recovery of communities. The organization has been directed by the Office of Emergency Management in New York to lead with feeding shelters through the City's Food Access Plan. A donation will help mobile canteen units being deployed to the areas hardest hit by Sandy.

The superstorm has also taken its toll on the pet population, with many families leaving their animals behind during evacuations and those harmed in Sandy's path. The American Society for the Prevention of Cruelty to Animals and the Humane Society of the United States both need donations to help support animals impacted with or without owners.
