Disclosed herein is a composition for removing odor, the composition including cucurbituril. The composition can capture and remove various kinds of odor materials (particularly, ammonium ion-containing bad odor, such as a fishy smell or the like) because cucurbituril can interact with various odor materials using its hydrophobic cavity and both inlets covered with carbonyl groups. Therefore, this composition can be practically applied to the cleaning of air and the improvement of an environment.
