A soup kitchen, food kitchen, or meal center is a place where food is offered to the hungry usually for free or sometimes at a below-market price. Frequently located in lower-income neighborhoods, soup kitchens are often staffed by volunteer organizations, such as church or community groups. Soup kitchens sometimes obtain food from a food bank for free or at a low price, because they are considered a charity, which makes it easier for them to feed the many people who require their services.

In politics, humanitarian aid, and the social sciences, hunger is defined as a condition in which a person does not have the physical or financial capability to eat sufficient food to meet basic nutritional needs for a sustained period. In the field of hunger relief, the term hunger is used in a sense that goes beyond the common desire for food that all humans experience, also known as an appetite. The most extreme form of hunger, when malnutrition is widespread, and when people have started dying of starvation through lack of access to sufficient, nutritious food, leads to a declaration of famine.
