Evidence for the strong elongation of clusters of galaxies is presented, and the relation between cluster shape and cluster environment is examined in an investigation of the origin of the aspherical shape of clusters. Position angles and ellipticities of 44 regular Abell clusters are determined using a procedure controlled by a Monte-Carlo method. The distribution of apparent cluster ellipticities is synthesized, and possible distributions of intrinsic cluster ellipticities are proposed. The strong alignment of clusters and first ranked cluster galaxies is confirmed, and it is found that neighboring clusters separated by less than about 30 Mpc, strongly tend to point to each other. The orientation of a cluster is significantly related to the distribution of surrounding clusters, indicating that the spatial distribution is anisotropic on a scale of about 100 Mpc.
