Abstract: We introduce the notion of the projective biquandle (an object related to links in projective space). The paper is devoted to the proof that for any link in projective space the number of addmissible colorings by projective biquandle of its diagram is invariant.

Keywords: link, invariant, biquandle, projective space.
