A Research lodge is a particular type of Masonic lodge which is devoted to Masonic research. It is a lodge, and as such has a charter from some Grand Lodge. However, it does not confer degrees, and restricts membership to Master Masons of some jurisdiction in amity with the jurisdiction that the research lodge is in. Related to research lodges are Masonic research societies, which serve the same purpose but function fundamentally differently. There are research lodges in most countries where Freemasonry exists.
