Humanitarian daily rations (HDRs) are food rations manufactured in the United States intended to be supplied to civilians and other non-military personnel in humanitarian crises. Each is intended to serve as a single person's full daily food supply, and contain somewhat over 2,200 calories (9,200 kJ). They have shelf-lives of about 3 years, and their contents are designed to be acceptable to a variety of religious and ethnic groups. The meals cost approximately one-fifth of the cost of a Meal, Ready-to-Eat (MRE). The rations were first used in Bosnia in 1993.

From the time they were created and used in 1993 until November 2001, HDRs were packaged with a bright yellow outer plastic covering; this choice of color, however, proved to be problematic in areas of the world where cluster bombs were being used, as the bombs were the exact same shade of yellow and recipients of the rations sometimes confused the ration package for undetonated cluster bombs, often spotting the bright color from a distance and making an incorrect assumption; this prompted the United States Federal Government to reissue the packages with a deep salmon pink outer covering to distinguish them from the bombs (this color has been used in the HDR manufacturing process ever since).

The meals are designed to be able to survive being air-dropped without a parachute. This is safer for refugees than parachuting large pallets of rations, as well as preventing meal hoarding by those able to seize a single, large delivery.

HDRs are also made available through organizations such as The Salvation Army to aid victims of poverty in the United States, and were distributed during Hurricane Katrina and Hurricane Rita to victims of the disasters by the Federal Emergency Management Agency (FEMA).
