Mount Suckling or Goropi, is the highest peak of the Goropu Mountains, part of the Owen Stanley Range in southeastern Papua New Guinea. It lies about east of Port Moresby. Situated on a relatively narrow peninsula, it lies only about from the sea to both the northeast (in the direction of Collingwood Bay) and the south. While not the highest peak in the Owen Stanley Range (Mount Victoria is the highest), it is the most topographically prominent peak in the range, and it is in fact the third most prominent peak on the island of New Guinea. The peak rises above the timberline, while its lower slopes are well-forested.
