This is a **list of axioms** as that term is understood in mathematics, by Wikipedia page. In epistemology, the word *axiom* is understood differently; see axiom and self-evidence. Individual axioms are almost always part of a larger axiomatic system.

*Together with the axiom of choice (see below), these are the* de facto *standard axioms for contemporary mathematics or set theory. They can be easily adapted to analogous theories, such as mereology.*

- Axiom of extensionality
- Axiom of empty set
- Axiom of pairing
- Axiom of union
- Axiom of infinity
- Axiom schema of replacement
- Axiom of power set
- Axiom of regularity
- Axiom schema of specification

See also Zermelo set theory.

*With the Zermelo–Fraenkel axioms above, this makes up the system ZFC in which most mathematics is potentially formalisable.*
