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
