Abstract: The present invention details a double-drinking-mouth portable cup, comprising a cup body. A cup cover is in threaded connection to the top of the cup body; a groove is formed in the top of the cup cover; and a cup mouth drinking structure is disposed in the groove. For the present invention, by disposing the cup mouth drinking structure and a sucking drinking structure on the top of the cup cover, the cup cover can have double drinking modes, so that the application range of the cup body may be enlarged, the use convenience of the cup body is greatly improved, and the problem that an existing water cup cannot meet the drinking demands in different environments due to relatively single structure and function and only one drinking mouth, so that the application range of the water cup is severely affected is solved.
