John Stow (also Stowe; 1524/25 – 5 April 1605) was an English historian and antiquarian. He wrote a series of chronicles of English history, published from 1565 onwards under such titles as The Summarie of Englyshe Chronicles, The Chronicles of England, and The Annales of England; and also A Survey of London (1598; second edition 1603). A. L. Rowse has described him as "one of the best historians of that age; indefatigable in the trouble he took, thorough and conscientious, accurate – above all things devoted to truth".

John Stow was born in about 1525 in the City of London parish of St Michael, Cornhill, then at the heart of London's metropolis. His father, Thomas Stow, was a tallow chandler. Thomas Stow is recorded as paying rent of 6s 8d per year for the family dwelling, and as a youth Stow would fetch milk every morning from a farm on the land nearby to the east owned by the Minoresses of the Convent of St Clare. There is no evidence that he ever attended a grammar school; his learning appears to have been largely self-acquired.

Stow did not take up his father's trade of tallow chandlery, instead becoming an apprentice, and in 1547 a freeman, of the Merchant Taylors' Company, by which stage he had set up business in premises close to the Aldgate Pump in Aldgate, near to Leadenhall Street and Fenchurch Street.

In about 1560 he started upon his major work, the Survey of London. His antiquarian interests attracted suspicion from the ecclesiastical authorities as a person "with many dangerous and superstitious books in his possession", and in February 1569 his house was searched. An inventory was made of all the books at his home, especially those "in defence of papistry", but he was able to satisfy his interrogators as to the soundness of his Protestantism. A second attempt to incriminate him was made in 1570 also without success.

In about 1570 he moved to the parish of St Andrew Undershaft in the Ward of Lime Street, where he lived in comfortable surroundings until his death in 1605.

Stow was in close contact with many of the leading antiquarians of his day, including Archbishop Matthew Parker, John Joscelyn, John Dee, William Fleetwood, William Lambarde, Robert Glover, Henry Savile, William Camden, Henry Ferrers and Thomas Hatcher. He was active in the first Society of Antiquaries, established in about 1586. He built up an extensive library of manuscript and printed historical sources, which became known to contemporaries as his "storehouse", and which he was generous in making available to others.

Stow was highly esteemed by his antiquarian contemporaries, probably in no small part because of his willingness to share his material. Sir George Buck wrote of "honest John Stow, who could not flatter and speak dishonestly, and who was a man very diligent and much inquisitive to uncover all things concerning the affairs or words or persons of princes", and characterised him as a "good antiquary and diligent searcher of knowledge". Edmund Howes described him in later life as being "of a pleasant and cheerful countenance; his sight and memory very good; very sober, mild, and courteous to any that required his instructions; and retained the true use of all his senses unto the day of his death, being of an excellent memory".

Nevertheless he was drawn into several bitter quarrels and harboured longstanding grudges. One protracted feud was with his younger brother, Thomas, over their respective shares in their mother's estate before and after her death in 1568. (John believed he was entitled to a greater share as the eldest son; Thomas claimed a greater share because he had cared for their mother during her final years.) He had further arguments with neighbours, including William Ditcher and a Mister Crowche. His quarrel with his rival chronicler Richard Grafton is noted below.
