Julia Peterkin (October 31, 1880 – August 10, 1961) was an American author from South Carolina. In 1929 she won the Pulitzer Prize for Novel/Literature, for her novel Scarlet Sister Mary. She wrote several novels about the plantation South, especially the Gullah people of the Low Country. She was one of the few white authors who wrote about the African-American experience.
Julia Mood was born in Laurens County, South Carolina. Her father was a physician, and she was the third of his four children. Her mother died soon after her birth, and her father later married Janie Brogdon. Janie was the mother of Henry Ashleigh Mood, Julia's half-brother and her father's fourth child. He became a doctor.
In 1896, at age 16, Julia Mood graduated from Converse College in Spartanburg, South Carolina; she earned her master's degree there a year later. She taught at the public school in Forte Motte, South Carolina, for a few years before she married William George Peterkin in 1903. He was a planter who owned Lang Syne, a 2,000-acre (8.1 km2) cotton plantation near Fort Motte.
Julia began writing short stories, inspired by the everyday life and management of the plantation. She was described as audacious as well as gracious by Robeson (1995). Peterkin sent highly assertive letters to people she did not know and had never met. For instance, she wrote to authors Carl Sandburg and H.L. Mencken, and included samples of her writing about the Gullah culture of coastal South Carolina. Living chiefly on the plantation, she invited Sandburg, Mencken, and other prominent people to the plantation.
Sandburg, who lived nearby in Flat Rock, North Carolina, made a visit. While Mencken did not visit, he became Peterkin's literary agent in her early career, a possible testament to her persuasive letters. Eventually, Mencken led her to Alfred Knopf, who published her first book, Green Thursday, in 1924.
