Bolus can mean:
- In digestion, a bolus (from Latin bolus, ball) is a round mass of organic matter moving through the digestive tract. A bolus is initially shaped through chewing and swallowing of food and maintained as peristalsis moves it through the intestines.
- The term "bolus" is also used in aerospace engineering to define the characteristics of human feces, when discussing devices for processing feces passed by a pilot while in space or air flight.
- A radio-frequency identification tag ingested by livestock is also referred to as a bolus. It remains in the stomach of the animal for its lifetime and emits a unique ID that can be used to track an animal.
