Siple Coast (-82°N -155°W) is the middle portion of the relatively ill-defined coast along the east side of the Ross Ice Shelf, between the north end of Gould Coast (-83.5°N -153°W) and the south end of Shirase Coast (-80.1667°N -151°W). The area was originally called Kirton Coast, but was renamed by NZ-APC in 1961 after Paul A. Siple, a noted American scientist-explorer who accompanied R. Admiral Richard E. Byrd on all of his Antarctic expeditions.
