Humanitarian daily rations (HDRs, "humrats") 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 contains somewhat over 2,200 calories (9,200 J). 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), or US$4.70 in 2012. The rations were first used in Bosnia in 1993 as part of Operation Provide Promise.

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, and prevents meal hoarding by those able to seize a single, large delivery.

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

Before the HDR was made available, the United States provided military Meal, Ready-to-Eat (MREs) to famine victims. Aid agencies complained that the MREs were too high in protein, indigestible, and violated religious taboos. In some cases, famine victims went into shock (see refeeding syndrome) after eating large MRE meals. By the time of the creation of the HDR, the Department of Defense had almost depleted its stock of MREs in the post–Gulf War period, having distributed 53 million MREs between 1990 and 1993. The end of the Cold War caused reductions in military funding, prompting the DoD to rethink its approach on aid. Furthermore, MRE producers found the profit in producing MRE "marginal" and wanted to expand to foreign and civilian markets. The HDR provided a solution to all these problems: it is safe to provide to famine victims, cheap enough to distribute broadly, and provides a large potential market to contractors.

The HDR packages are delivered in cases of packages. Each contains a small selection of food items based on predetermined menus, and an accessory pack containing red pepper, pepper, salt, sugar, spoon, matches, an alcohol-free moist towelette, and a napkin.

HDRs are typically air-dropped into the disaster area on large pallets. 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 proved to be problematic in areas of the world where cluster bombs were being used, as the bombs were the same shade of yellow. 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. Later packages were covered in salmon colored foil.

HDRs produced in the United States are manufactured by the same companies that produce MREs designed for the United States Armed Forces. Like MREs, the food components are designed so they can be consumed without requiring additional preparation, including cooking. They do not include flameless ration heaters, which are found in MREs.

There are five menus of HDR. Each menu contains three sub-menus, printed as list-of-content A, B, and C on the packet. Each HDR packet randomly contains two of the sub-menus.
