A model is a pattern, plan, representation (especially in miniature), or description designed to show the main object or workings of an object, system, or concept. Model may also refer to:

Abstractions, concepts, and theories:

• Model (abstract), an abstraction or conceptual object used in the creation of a predictive formula
• Causal model, an abstract model that uses cause and effect logic
• Mathematical model, an abstract model that uses mathematical language
• Statistical model, in applied statistics, a parameterized set of probability distributions
• Model theory, study of the representation of mathematical concepts
• Meta-modeling, a model of a model
• Computer model, a computer program which attempts to simulate an abstract model of a particular system
• Data model, a description of the structure of a database
• Scientific modelling, the process of generating abstract models
• The Standard Model, the theory in particle physics which describes certain fundamental forces and particles
• Model building (particle physics), the construction of new models beyond the Standard Model in particle physics
• Molecular modelling, methods and techniques to model the behaviour of molecules
• Geologic modelling, the applied science of creating computerized models of geologic features
• A pre-clinical development model of a biological process, used in biological or medical research
• Model Driven Engineering, the systematic use of models in engineering
• Morphological modelling, a problem-solving technique used for problems with which causal modelling does not function well
• Similitude (model), in engineering, used in the scientific testing of physical models
• Working Model, engineering software
• Model (economics), a theoretical construct representing economic processes
• Model (macroeconomics), an economic model representing a national or regional economy
• Business model, a framework expressing the business logic of a firm
• Model-view-controller, an architectural pattern in software engineering
• Toy model, a simplified system that illustrates or exhibits the same behaviour as the more complex, general system

As representations of objects:

• Model (physical), a physical representation of an object
• Solid modeling, study of unambiguous representations of the solid parts of an object
• Scale model, a replica or prototype of an object
• Model building, a hobby centered around construction of material replicas
• 3D model, a 3D polygonal representation of an object, usually displayed with a computer

In human and animal behavior

• An organism (or set of signals originating from it) that is mimicked by another.
• Mental model, a person's cognitive representation of an idea or thought process
• Modeling (NLP), a process in neuro-linguistic programming
• Modelling (psychology), learning by imitating or observing a person's behavior
• Role model, a person who serves as a behavioural or moral example to others

In occupations:

• Model (person), a person employed to display his or her looks or something such as a commercial product, e.g., a fashion model (see also supermodel). Subcategories include:
  • Model (art), a person who poses to be depicted in art, for example in art school
  • Promotional model, a person who interacts with consumers to draw attention to and often inform them about a product
  • Fetish model, a model who wears the clothing and/or devices of sexual fetishes

• Modeling (lighting) means how a key light reveals the three-dimensional form of a subject
• Modeling light, a continuous light source that visualizes the effect of a photographic flash
