The utility model relates to a sanitary cover for a cigarette. The existing sanitary covers for a cigarette are disposable products, which lead to the defects that resources are wasted, and bacteria contamination occurs at the time of follow-up smoking. Thereby, the sanitary cover for a cigarette is divided into two parts in order to overcome the defects of the existing sanitary covers for a cigarette. Both ends of a cover body are hollow, and a cover cap forms a U shape corresponding to the cover body. When smoking has to be ceased or is stopped because a thing occurs in the midway, the cover body and the cover cap are recombined together so as to seal and protect a cigarette holder. As a result, cigarette waste does not occur, the sanitary cover can be disassembled for continual use, and sanitary conditions are ensured. The utility model has the advantages of simple structure, convenience, and practicality.
