Trachea is a common biological term for an airway through which respiratory air transport takes place in organisms.
- Vertebrate trachea, in terrestrial vertebrates, such as birds and humans, the trachea lets air move from the throat to the lungs
- Invertebrate trachea, in terrestrial invertebrates, such as onychophorans and insects, tracheae conduct air from outside the organism directly to all internal tissues
