Thomas R. G. Green (born 1941) is a British cognitive scientist, and Visiting Professor at the University of York, known for his contribution to cognitive modelling and the development of the concept of cognitive dimensions of notations.

In the 1980s Green was working for MRC Applied Psychology Unit in Cambridge, and became reader in computing at the Open University. In 2015 he is Visiting Professor at the Department of Computer Science of the University of York, and is affiliated with the Department of Computer Science of the University of Leeds.

His research interests reaches from "Programming language design and cognitive psychology", "Interaction as an action language", and "Cognitive dimensions of notations and devices" to "Models of information artifacts" and "Virtual devices as research tools."
