DUKW（又名DUCK，鸭子）是二战时期盟军的6轮两栖装甲车，由通用动力（GMC）制造，二战时用于运载物资及部队穿越水陆及登陆作战用途，二战后改为运载游客作旅游用途。

DUKW由斯帕克曼与斯蒂芬公司（Sparkman & Stephens）的游艇设计师Dennis Puleston（英国水兵）及Frank W. Speir（麻省理工学院ROTC中尉）设计，国防研究院（National Defense Research Committee）及美国国家科学基金会（Office of Scientific Research and Development）开发，DUKW的车身设计深受福特GPA两栖吉普车的影响，如同是GPA的放大，DUKW的车尾有水上行驶用的螺旋桨和船舵，其车身内部结构设计则来自CCKW-353卡车。

The DUKW (colloquially known as Duck) is a six-wheel-drive amphibious modification of the 2-ton capacity CCKW trucks used by the U.S. military in World War II. Designed by a partnership under military auspices of Sparkman & Stephens and General Motors Corporation (GMC), the DUKW was used for the transportation of goods and troops over land and water. Excelling at approaching and crossing beaches in amphibious warfare attacks, it was intended only to last long enough to meet the demands of combat. Surviving DUKWs have since found popularity as tourist craft in marine environments.
