The invention provides a water storing and icing device for an ice skating rink. The water storing and icing device for the ice skating rink includes a bottom wall, a sidewall, a plurality of fixing parts, and a plurality of fixing members. The sidewall is connected to and surrounds the bottom wall to form a containing space for storing and icing water. The fixing parts are disposed at an outer side of the sidewall. The fixing members are correspondingly connected to the fixing parts and adapted to be connected to the ground. When the containing space is being used to store and ice water, the fixing members support the sidewall, such that the sidewall stands on the bottom wall, and the fixing members are removed after water is frozen in the containing space, so as to use the water storing and icing device as the ice skating rink.
