The Mayener mining field, more rarely also called Mayener Lay/Ley(en), is a former mining area for basalt rock (Mayener basalt lava) on the northeastern edge of the town of Mayen in the eastern Vulkaneifel (Vordereifel) in Rhineland-Palatinate.

For more than 7,000 years, from the Neolithic period to modern times, the hard and porous rock has been mined here primarily for the production of grinding stones and millstones, but also as stone and as a building material. For this purpose, several open quarries as well as numerous shafts and underground tunnels were excavated in the mining field.

After the underground mining ended, local breweries temporarily used the tunnels created as rock cellars for storing beer.

Since the surface quarries ceased operations in the 1970s due to inefficiency, nature has reclaimed the area — it is now overgrown with vegetation and numerous lakes have formed. The mining field offers a habitat for numerous, sometimes threatened, plant and animal species. The area with its numerous large and small caves is particularly important as a wintering and swarming quarters for bats.

The pit field is part of the Volcano Park in the Laacher See National Geopark and the German Volcano Road. Interested visitors are presented with the natural features and history of the place in an information center (“Experience Grubenfeld”). A sculpture park (“Lapidea”), made from locally mined rock, complements the exhibition.
