A safe tablet cutting device includes a container, a cover, a cutter, and a suspension body. A platform in the container provides tablet positioning. First and second positioning elements are configured between a back end of the container and the platform. The cover is hinged to the back end of the container. The suspension body has its back end freely rotatable but confined between the first and second positioning elements when the cover is opened or closed. The suspension body has a slot opening corresponding to the cutter configured on the inside of the cover so that the cutter is properly concealed behind the suspension body and, when the cover is closed, gradually exposed to cut the tablet. The safety and applicability of the tablet cutting device is as such enhanced.
