Mikveh or mikvah is a bath used for the purpose of ritual immersion in Judaism to achieve ritual purity.
After the destruction of the Temple, the mikveh's main uses remained as follows:
- by Jewish women to achieve ritual purity after menstruation or childbirth before they and their husbands may resume marital relations;
- by Jewish men to achieve ritual purity (see details below);
- as part of the traditional procedure for conversion to Judaism;
- to immerse newly acquired utensils used in serving and eating food.
