There are several proposed types of '''exotic matter''':

* [[Hypothetical particle]]s and states of matter that have not yet been encountered, but whose properties would be within the realm of mainstream physics if found to exist. 
* Several particles whose existence has been experimentally confirmed that are conjectured to be [[exotic hadron]]s and within the [[Standard Model]].
* [[State of matter|States of matter]] that are not commonly encountered, such as [[Bose–Einstein condensate]]s, [[fermionic condensate]]s, [[nuclear matter]], [[quantum spin liquid]], [[string-net liquid]], [[supercritical fluid]], [[color-glass condensate]],  [[quark–gluon plasma]], [[Rydberg matter]], [[Rydberg polaron]], [[photonic matter]], [[Wigner crystal]],<ref>{{Cite journal |last=Tsui |first=Yen-Chen |last2=He |first2=Minhao |last3=Hu |first3=Yuwen |last4=Lake |first4=Ethan |last5=Wang |first5=Taige |last6=Watanabe |first6=Kenji |last7=Taniguchi |first7=Takashi |last8=Zaletel |first8=Michael P. |last9=Yazdani |first9=Ali |date=2024-04-10 |title=Direct observation of a magnetic-field-induced Wigner crystal |url=https://www.nature.com/articles/s41586-024-07212-7 |journal=Nature |language=en |volume=628 |issue=8007 |pages=287–292 |arxiv=2312.11632 |doi=10.1038/s41586-024-07212-7 |issn=1476-4687}}</ref> [[Superfluidity|Superfluid]] and [[time crystal]] but whose properties are entirely within the realm of mainstream physics.
* Forms of matter that are poorly understood, such as [[dark matter]] and [[mirror matter]].
* Ordinary matter that when placed under [[high pressure]], may result in dramatic changes in its physical or chemical properties.
* [[Degenerate matter]]
* [[Exotic atom]]s
