## Abstract In this paper, we investigate Hadamard matrices of order 2(p + 1) with an automorphism of odd prime order __p__. In particular, the classification of such Hadamard matrices for the cases __p__ = 19 and 23 is given. Self‐dual codes related to such Hadamard matrices are also investigated.
