The Invisible College was the name given to themselves by a group of like-minded scientists and natural philosophers in England in the mid-17th century. The informal association is considered to have been one of the origins of the Royal Society.

The purpose of the invisible college was to encourage each other to develop scientific knowledge through experiments and other kinds of investigation.

Some of the members of the Invisible College were among the founders of the Royal Society in 1660, including Robert Boyle, John Wilkins and Samuel Hartlib.
