A quadrangular prism of self-invisibility is originally reported in this paper. It is a self-invisible unit, which does not depend on any outer refractive materials or reflective mirrors. Four identical triangular prisms with the lateral faces of mirrors, divided into two groups, are symmetrically placed on two transparent rectangular prisms in a symmetrical way. Two identical rectangular prisms serve as the lateral faces of a quadrangular prism. Two incident beams, parallel to the rectangular

One of the potential applications will be mentioned briefly.
