The Rocky Mountain Map Society is a non-profit organization dedicated to the study and appreciation of maps and other items of cartographic interest. The Society was formed in 1991 and is based in Denver, Colorado.

Most meetings are held on Tuesday evenings at the Denver Public Library, 5th Floor, Gates Room, at 5:30 PM.


Members of the Rocky Mountain Map Society are from a variety of backgrounds. Most are map collectors and some members are professionals in the field of cartography, but all have an interest in history. The common thread is a fascination with maps, from the first cartographic attempts to the most recent developments.

The Rocky Mountain Map Society actively promotes and sponsors events of interest to map enthusiasts.
