Margery Kempe (c. 1373 – after 1438) is known for writing The Book of Margery Kempe, a work considered by some to be the first autobiography in the English language. This book chronicles, to some extent, her extensive pilgrimages to various holy sites in Europe and Asia.

She was born Margery Brunham in King's Lynn (then Bishop's Lynn), Norfolk, Kingdom of England and married at the age of 20 to a local man named John Kempe, with whom she had 14 children. Her father, John Brunham, was a merchant in Lynn, five-time mayor, Member of Parliament and merchant whose fortunes may have been negatively affected by downturns in the economy, especially in the wool trades, of the 1390s.

Following the birth of her first child, Margery fell ill and feared for her life. After a failed confession that resulted in a bout of self-described "madness," Margery Kempe claimed to have had a vision that called her to leave aside the "vanities" of this world. Having for many weeks railed against her family, and friends, Kempe reports that she saw a vision of Jesus Christ at her bedside, asking her "Daughter, why hast thou forsaken Me, and I forsook never thee?" From that point forward, Kempe undertook two failed domestic businesses — a brewery and a grain mill — both common home-based businesses for medieval women.

Though she had tried to be more devout after her vision, she was tempted by sexual pleasures and social jealousy for some years. Eventually turning away from what she interpreted as the effect of worldly pride in her vocational choices, Kempe dedicated herself completely to the spiritual calling that she felt her earlier vision required. Striving to live a life of commitment to God, Kempe negotiated a chaste marriage with her husband, and began to make pilgrimages around Europe to holy sites — including Rome, Jerusalem, and Santiago de Compostela. The stories surrounding these travels are what eventually comprised much of her Book, although a final section includes a series of prayers. The spiritual focus of her Book is the mystical conversations she conducts with Christ for more than forty years.

From 1413 to 1420, Margery also visited important sites and people in England, including Philip Repyngdon the Bishop of Lincoln, Henry Chichele the Archbishop of Canterbury, and Julian of Norwich. She also went to Rome, where she stayed at the Venerable English College in 1416. Her thoughts concerning these trips and her revelatory experiences make up much of her book, but a key focus is also her persecution by civil and religious leaders. The last section of her book deals with a journey in the 1430s to Norway and the Holy Roman Empire, where she visited the Holy Blood of Wilsnack. Two different scribes did the writing for Margery, under her strict supervision.
