Helmet for My Pillow is the personal narrative written by World War II United States Marine Corps veteran, author, and military historian Robert Leckie.

First published in 1957, the story begins with Leckie's enlisting in the United States Marines shortly after the 1941 attack on Pearl Harbor.

"[1] The HBO mini-series The Pacific (2010) was adapted in large part from Helmet for My Pillow, along with Eugene Sledge's With the Old Breed: At Peleliu and Okinawa, and the personal story of Medal of Honor recipient Gunnery Sergeant John Basilone.

Leckie is assigned to the 1st Marine Division and is deployed to Guadalcanal, Melbourne Australia, New Guinea, Cape Gloucester, before being evacuated with wounds from the island of Peleliu.

Sledge's With the Old Breed: At Peleliu and Okinawa, along with Helmet for My Pillow, formed the basis for the HBO miniseries The Pacific, the successor to Band of Brothers.
