Margie Stewart (December 14, 1919 – April 26, 2012) was the official United States Army poster girl during World War II. She appeared on twelve posters, of which a total of 94 million copies were distributed.
She was born in Wabash, Indiana and attended Indiana University. She became a model and appeared in about 20 RKO movies, often in uncredited roles. Among her roles was that of Marjorie Forrester, Throckmorton P. Gildersleeve's niece, in Gildersleeve's Ghost.
In addition to appearing in the posters, Stewart toured the U.S. as one of the four members of a group called the Bondbardiers, accompanied by various Hollywood stars, to sell war bonds. In 1945, she toured Europe and was one of the first civilians to enter Germany after the end of the war. Her appearance in London's Hyde Park "caused gridlock."
