'''Matrix model''' may refer to:
== Mathematics and physics ==
* In [[theoretical physics]], a matrix model is a system (usually a [[quantum mechanics|quantum mechanical]] system) with [[matrix (mathematics)|matrix]]-valued [[physical quantity|physical quantities]]. See, for example, [[Lax pair]].
* The "old" matrix models are relevant for [[string theory]] in two [[spacetime]] dimensions. The "new" matrix model is a synonym for "[[matrix theory (physics)|matrix theory]]."
* A concept from [[algebraic logic]].
* a model using a [[Matrix (mathematics)|matrix]] in mathematics
== Biomedicine ==
* [[Matrix populationtheory models(physics)]], area usedquantum tomechanical model wildlife and human population dynamics.
* [[Matrix population models]], a type of population model that uses matrix algebra
* The [[Matrix Model of substance abuse treatment]] is a model developed by the Matrix Institute on Addictions in the 1980s to treat [[cocaine]] and [[methamphetamine]] addiction.
* [[Matrix management]], an organizational structure
* Protein complexes: a matrix model of protein complexes (unrealistically) predicts that all proteins in a complex interact with all other proteins. Mathematically, a matrix model of a protein complex is a [[complete graph]].

== Management and economics ==
* [[Matrix (disambiguation)]]
* The term "matrix model" is used to describe [[matrix management]] where each worker in an organisation has two managers, one "functional": managing their expertise, the other "executive": managing their work on a project.
