The Encyclopædia Edinensis was a six-volume general encyclopedia published in Edinburgh in 1827, and intended for a popular audience. It was edited by James Millar, who died just before it was complete.
Editorial staff 
- James Millar, principal editor
- Jeremiah Kirby and Richard Poole, main editors and contributors. Poole wrote articles on "Mental Diseases".
- John Sommers, minister at Falkirk, was proprietor and also editor for the last three volumes.
The editorial line was quite sympathetic to phrenology. According to the Phrenological Journal, Sommers approved the inclusion of the uncritical article "Phrenology". Poole in 1819 wrote for the encyclopedia an article on education, an early treatment from the point of phrenology.
