Carcassonne: Die Kornkreise (The Corn Circles/The Crop Circles), the seventh official mini-expansion for Carcassonne, consists of six tiles depicting corn circles made from corn stalks. A corn circle tile allows a player to place a second follower on a feature that they have already claimed, or to return an already-placed follower to his supply.

Carcassonne: Die Kornkreise first appeared in Germany as a bonus expansion shrinkwrapped to the Carcassonne base game, and was later available directly from the publisher Hans im Glück.

A second set of six Carcassonne: Die Kornkreise (Carcassonne: Corn Circles II) tiles come packaged in six mini-expansions for Carcassonne – one tile per expansion – released by Hans im Glück and 999 Games. These tiles can be used on their own or combined with the tiles from the first Carcassonne: Die Kornkreise expansion. Part of the Carcassonne series.
