The invention provides a refrigerator door body and a refrigerator, and belongs to the technical field of household appliances. The refrigerator door body comprises a door main body and at least one bottle holder. The door main body is provided with a door lining. A plurality of door lining limiting assemblies and bottle holder clamping assemblies are further included at the position of the refrigerator door body. The multiple door lining limiting assemblies are arrayed along the two sides of the door lining. Each door lining limiting assembly comprises a limiting fixation part fixed to the inner side of the door lining and a limiting body connected to the limiting fixation part in a telescoping mode. The bottle holder clamping assemblies are arranged at the two sides of each bottle holder. The limiting bodies extend out of the ends of the limiting fixation parts and further protrude out of the surface of the door lining and thus the bottle holder heights can be adjusted by placing thebottoms of the bottle holder clamping assemblies onto the limiting bodies of different heights. According to the refrigerator door body and the refrigerator, the bottle holders can be installed and meanwhile the heights of the bottle holders can be adjusted; and more objects of different dimensions can be put onto the bottle holders, the space of the refrigerator is fully utilized, and the spaceutilization rate of the refrigerator is increased.
