A cooling cigarette filter and a cigarette are disclosed. The cooling cigarette filter comprises a cooling section (2). The cooling section (2) comprises a cooling stick (201) formed from paper (5). The cooling stick (201) has one or more holes (202) communicating two ends of the cooling stick. And the surface of the paper (5) is coated with a cooling material. The cooling cigarette filter has the advantages of ensuring the amount of smoke and lowering the temperature of the smoke entering the mouth. Through the combination design of the structure of the cooling stick and the type and amount of the cooling material, the smoke can flow out of a smoke generation section rapidly and smoothly And the temperature of the high-temperature smoke before entering the mouth can be significantly lowered, thereby improving the comfort and satisfaction of smoking.
