雷尼克冰川是南极洲的冰川，全长约320公里，宽30至50公里，发源自梅萨山脉以西的南极高原，该冰川的上游在1960年由美国探险队发现。

Rennick Glacier is broad glacier, nearly 200 miles long, which is one of the largest in Antarctica. It rises on the polar plateau westward of Mesa Range and is 20 to 30 miles wide, narrowing to 10 miles near the coast. It takes its name from Rennick Bay where the glacier reaches the sea. The seaward part of the glacier was photographed by U.S. Navy (USN) Operation Highjump, 1946-47. The upper reaches of the Rennick Glacier were discovered and explored by the U.S. Victoria Land Traverse (VLT) in February 1960, and the first ascent made of Welcome Mountain by John Weihaupt, Alfred Stuart, Claude Lorius and Arnold Heine of the VLT party. On February 10, 1960, Lieutenant Commander Robert L. Dale, pilot of U.S. Navy (USN) Squadron VX-6, evacuated the VLT from 7238S, 16132E, on this glacier, and then conducted an aerial photographic reconnaissance to Rennick Bay on the coast before returning the VLT team to NAF McMurdo.
