In the present paper, a bivariate generalization of the Meyer-Konig and Zeller operators based on the q-integers is constructed. Approximation properties and rate of convergence of these operators are established with the help of a Korovkin theorem for bivariate functions and a Korovkin-type theorem given by Heping [81 and Volkov [ 14] respectively.
