Abstract: An anti-overflow pot lid is provided, including: a lid body configured to be curved to protrude, and to cover an opening of a pot body; a recessed portion configured to be recessed downward from the lid body; one or more inlet holes configured to be formed at an upper part of the recessed portion and let in steam generated in the pot body; and one or more outlet holes configured to be formed at a lower part of the recessed portion and let out water drops obtained by liquefying the steam into the pot body. The anti-overflow pot lid can effectively prevent rattling and spillage or leakage.
