Corpuscle is an archaic term that has several meanings:
- a small free floating biological cell, especially ones occurring in blood.
- a nerve ending such as Meissner's corpuscle or a Pacinian corpuscle
- a subatomic particle similar to the electron. This term was first proposed in the paper: Thomson, J.J. (June 1906). "On the Number of Corpuscles in an Atom". Philosophical Magazine.
- a single, infinitesimally small, particle of light. Isaac Newton proposed this term to represent a concept that was quite different from the idea of a photon.
