Burping (also called belching and eructation) is the release of gas from the upper digestive tract (esophagus and stomach) of animals through the mouth. It is usually audible.

In humans, burping can be caused by normal eating processes, or as a side effect of other medical conditions. There is a range of levels of social acceptance for burping: within certain context and cultures, burping is acceptable, while in others it is offensive or unacceptable. Failure to burp can cause pain or other negative effects.

Humans are not the only animals that burp: it is very common among other mammals. In particular, burping by domesticated ruminants, such as cows or sheep, is a major contributor of methane emissions which cause climate change and have a negative effect on the environment. Significant research is being done to find mitigation strategies for ruminant burping, i.e. modifying the animals' diets with Asparagopsis taxiformis (red seaweed).
