Donald Gilbert Cook (August 9, 1934 – December 8, 1967) was a United States Marine Corps officer and a Medal of Honor recipient.

Repeatedly assuming more than his share of responsibility for their health, Colonel Cook willingly and unselfishly put the interests of his comrades before that of his own well-being and, eventually, his life.

Giving more needy men his medicine and drug allowance while constantly nursing them, he risked infection from contagious diseases while in a rapidly deteriorating state of health.

Rather than negotiate for his own release or better treatment, he steadfastly frustrated attempts by the Viet Cong to break his indomitable spirit and passed this same resolve on to the men whose well-being he so closely associated himself.

His personal valor and exceptional spirit of loyalty in the face of almost certain death reflected the highest credit upon Colonel Cook, the Marine Corps, and the United States Naval Service.The United States Navy Arleigh Burke-class guided missile destroyer USS Donald Cook (DDG-75) is named in his honor.
