Humanitarian aid is material and logistic assistance, usually in the short-term, to people in need. Among the people in need are the homeless, refugees, and victims of natural disasters, wars, and famines. The primary objective of humanitarian aid is to save lives, alleviate suffering, and maintain human dignity.

While often used interchangeably, humanitarian aid and humanitarian assistance are distinct concepts. Humanitarian aid generally refers to the provision of immediate, short-term relief in crisis situations, such as food, water, shelter, and medical care. Humanitarian assistance, on the other hand, encompasses a broader range of activities, including longer-term support for recovery, rehabilitation, and capacity building. Humanitarian aid is distinct from development aid, which seeks to address underlying socioeconomic factors.

Humanitarian aid can come from either local or international communities through international non-governmental organizations (INGOs). In reaching out to international communities, the Office for the Coordination of Humanitarian Affairs (OCHA) of the United Nations (UN) is responsible for coordination responses to emergencies. It taps to the various members of Inter-Agency Standing Committee, whose members are responsible for providing emergency relief. The four UN entities that have primary roles in delivering humanitarian aid are United Nations Development Programme (UNDP), the United Nations Refugee Agency (UNHCR), the United Nations Children's Fund (UNICEF) and the World Food Programme (WFP).

According to the Global Humanitarian Overview of OCHA, nearly 300 million people need humanitarian assistance and protection in 2024, or 1 out of 27 people worldwide. In 2024, the estimated global humanitarian response requirements amount to approximately US$46.4 billion, targeting around 188 million of the most vulnerable people in 69 countries. The three major drivers of humanitarian needs worldwide are conflicts, climate-related disasters, and economic factors.

Food aid is a type of aid whereby food that is given to countries in urgent need of food supplies, especially if they have just experienced a natural disaster. Food aid can be provided by importing food from the donor, buying food locally, or providing cash.

The welfare impacts of any food aid-induced changes in food prices are decidedly mixed, underscoring the reality that it is impossible to generate only positive intended effects from an international aid program.^{[citation needed]} Although food aid constitutes a significant part of humanitarian assistance, evidence also suggests that it can initiate or amplify violent conflicts in the recipient countries.

Food aid that is relatively inappropriate to local uses can distort consumption patterns. Food aid is usually exported from temperate climate zones and is often different than the staple crops grown in recipient countries, which usually have a tropical climate. The logic of food export inherently entails some effort to change consumers' preferences, to introduce recipients to new foods and thereby stimulate demand for foods with which recipients were previously unfamiliar or which otherwise represent only a small portion of their diet.

Massive shipments of wheat and rice into the West African Sahel during the food crises of the mid-1970s and mid-1980s were widely believed to stimulate a shift in consumer demand from indigenous coarse grains – millet and sorghum – to western crops such as wheat. During the 2000 drought in northern Kenya, the price of changaa (a locally distilled alcohol) fell significantly and consumption seems to have increased as a result. This was a result of grain food aid inflows increasing the availability of low-cost inputs to the informal distilling industry.
