A subset of nodes S ⊆V of a graph G =(V , E ) is a dominating clique if S is a dominating set and a clique of G . The phase transition of dominating cliques in Erdös-Rényi random graph model is investigated in this paper. Lower and upper bounds on the edge probability p for the existence of an r -node dominating clique are established in this paper. We prove therein that given an n -node random graph G from for r =c log1/p n with 1≤c ≤2 it holds: (1) if p 1/2 then an r -clique is dominating in G with a high probability and, (2) if $p \leq ( 3 - \sqrt{5})/2$ then an r -clique is not dominating in G with a high probability. The remaining range of the probability p is discussed with more attention. Within such a range, we provide intervals of r where a dominating clique existence probability is zero, positive but less than one, and one, respectively.
