We generalize univariate multipoint evaluation of polynomials of degree n at sublinear amortized cost per point. More precisely, it is shown how to evaluate a bivariate polynomial p of maximum degree less than n, specified by its n2 coefficients, simultaneously at n2 given points using a total of O(n2.667) arithmetic operations. In terms of the input size N, being quadratic in n, this amounts to an amortized cost of O(N0.334) per point.
