Bottle keep (ボトルキープ botorukīpu, a wasei-eigo term), or "bottle-keep", is a service which is provided at some Japanese drinking establishments where a patron can purchase a bottle of liquor and have the unfinished portion stored until a later visit. A bottle retained in this manner is called a "keep bottle". The service is offered by a variety of drinking establishments, from casual izakaya to bars in some first-class hotels. For regular customers, the system is less expensive than paying for single drinks. Some restaurants and bars outside of Japan have also adopted the service.

Many of these bars have a bottle-keep system for regular patrons, who buy a bottle from time to time, as it is less expensive than paying for single drinks for a long run.
