USS Megrez (AK-126) was a Crater-class cargo ship commissioned by the US Navy for service in World War II.

[4] Megrez returned to Pearl Harbor on 2 June 1944, and took on a cargo of rolling stock, sheet metals, and ammunition for transportation to the Marianas in support of Saipan and Tinian operations.

Leaving Hawaiian waters on 19 June 1944, Megrez steamed, via Kwajalein and Eniwetok, for Saipan, arriving on 14 August 1944.

Megrez served in this capacity for the next 7 months, supplying this vital fluid to the warships as they pressed closer to the enemy's home islands.

[4] She was placed in the National Defense Reserve Fleet, Suisun Bay Group, until purchased by Zidell Exploration, Inc., on 13 June 1974, for $175,679.97, under a "nontransportation use" (NTU) contract.
