John Dury New (August 12, 1925 – September 25, 1944) was a United States Marine who for his gallantry in action at the cost of his life on Peleliu, posthumously received the Medal of Honor.

In September 1942, Private New joined the 4th Replacement Battalion, Fleet Marine Force, Training Center, at San Diego, California.

The President of the United States takes pride in presenting the MEDAL OF HONOR posthumously to for service as set forth in the following CITATION: "For conspicuous gallantry and intrepidity at the risk of his own life above and beyond the call of duty while serving with the Second Battalion, Seventh Marines, First Marine Division, in action against enemy Japanese forces on Peleliu Island, Palau Group, 25 September 1944.

When a Japanese soldier emerged from a cave in a cliff directly below an observation post and suddenly hurled a grenade into the position from which two of our men were directing mortar fire against enemy emplacements, Private First Class New instantly perceived the dire peril to the other Marines and, with utter disregard for his own safety, unhesitatingly flung himself upon the grenade and absorbed the full impact of the explosion, thus saving the lives of the two observers.

Private First Class New's great personal valor and selfless conduct in the face of almost certain death reflect the highest credit upon himself and the United States Naval Service.
