Let Sn, n
1, be a random walk on a polynomial hypergroup (N0, *), that is, a Markov chain on the nonnegative integers with stationary transition probabilities Pij =
i* µ({j}), where µ is a fixed probability measureon N0. Under certain conditions on this measure, the principle of large deviations is shown for the distributions of Sn/n. This result comprises the large deviation principle for birth and death random walks associated with the polynomials generating the polynomial hypergroup.
