Mary Vere (1581–1671) was an English letter writer.

She was born Mary Tracy, a daughter of Sir John Tracy (died 1591) of Toddington, Gloucestershire and his wife Anne, a daughter of Thomas Throckmorton (died 1568).^[1] Her brother Sir Thomas Tracy was a member of the household of Anne of Denmark, as an usher of her privy chamber.^[2]

She married firstly, William Hoby (died 1603). They had two children.

In October or November 1607, she married the veteran soldier Horace Vere.^[2]

Their children included:

Mary Vere was a Puritan. She wrote "God will provide" at the front of most of the books in her closet.^[3] In 1608 she donated a book to Sir Thomas Bodley's library, and asked that it be inscribed in Latin as a gift from the daughter of Sir John Tracy.^[4] A number of religious works were dedicated to her.^[5]

She was widowed in 1635. Mary Vere lived at Hackney. Her chaplain Samuel Rogers kept a diary. He much preferred her to Margaret Denny, the widow of Edward Denny, his previous patron.^[6]

At the death of the widow of Lord Vere's eldest brother, John Vere, she inherited Kirby Hall, where she died on Christmas Eve 1671, aged 90.
