Gloria Hemingway (born Gregory Hancock Hemingway, November 12, 1931 – October 1, 2001) was an American physician and writer who was the third and youngest child of author Ernest Hemingway.

A good athlete and a crack shot, Gloria longed to be a typical Hemingway hero and trained as a professional hunter in Africa, but her alcoholism prevented her gaining a license, as it also cost her her medical license in America. Gloria maintained a long-running feud with her father, stemming from a 1951 incident when her arrest for entering a bar "in drag" caused an argument between Ernest and Gloria's mother Pauline. Pauline died from an stress-related condition the next day, which Ernest blamed on Gloria and Gloria later believed to have been caused by Ernest. Her bestselling 1976 memoir of her father, Papa: A Personal Memoir, was seen by some to reflect troubles of her own. These included wearing women's clothes, which she ascribed to gender dysphoria.
