Biological models are experimental systems that recreate aspects of human tissue function or disease. For example, certain tumour cell lines may serve as cancer models, and transgenic mice that express human beta-amyloid protein may serve as animal models of Alzheimer's disease.

A biological model is an organism or system representing a more complex biological entity. It may refer to: a model organism, a non-human species that is extensively studied to understand particular biological phenomena present in many related organisms. an in vitro model system, representing complex in vivo systems.
