# Exclusion principle

Exclusion principle may refer to:

* Exclusion principle (philosophy), epistemological principle
* In economics, the exclusion principle states "the owner of a private good may exclude others from use unless they pay."; it excludes those who are unwilling or unable to pay for the private good, but does not apply to public goods that are known to be indivisible: such goods need only to be available to obtain their benefits rather than purchased
* Pauli exclusion principle, quantum mechanical principle
