Landing Zone (LZ) Liz was a forward support base for the US Marines and later for the US Army during the Vietnam War.

LZ Liz was located in Quang Ngai Province, I Corps, south of Da Nang and Chu Lai, west of Highway 1, north of LZ Bronco and Đức Phổ.

In July 1968 C battery, 1st Battalion, 82nd Field Artillery Regiment was deployed to LZ Liz and the guns were moved from the saddle to the eastern hill facing the South China Sea.

The 1/82nd supplied support for the Đức Phổ Base Camp and the field troops of the 1/20th.

The access road also became a time bomb as undetectable mines were planted.
