James Hargreaves (c. 1720 – 22 April 1778) was a weaver, carpenter and inventor in Lancashire, England. He was one of three inventors responsible for mechanizing spinning. Hargreaves is credited with inventing the spinning jenny in 1764, Richard Arkwright patented the water frame in 1769, and Samuel Crompton combined the two creating the spinning mule a little later.

James Hargreaves was born at Stanhill, Oswaldtwistle in Lancashire. He was described as "stout, broadest man of about five-foot ten, or rather more". He was illiterate and worked as a hand loom weaver during most of his life. He married and baptismal records show he has 13 children, of whom the author Baines in 1835 was aware of '6 or 7'. He was survived by eight children.

The idea for the spinning jenny is said to have come from the inventor seeing a one-thread wheel overturned upon the floor, when both the wheel and the spindle continued to revolve. He realized that if a number of spindles were placed upright and side by side, several threads might be spun at once. The spinning jenny was confined to producing cotton weft, it was unable to produce yarn of sufficient quality for the warp. High quality warp was later supplied by Arkwright's spinning frame.

Hargreaves produced the Jenny for himself but sold a few to neighbors.

The jenny was initially welcomed by the hand spinners, but when the price of yarn fell the mood changed.

Opposition to the machine caused Hargreaves to leave for Nottingham, where the cotton hosiery industry benefited from the increased provision of suitable yarn. Arkwright also ended up in the town, and was even more successful. Hargreaves made jennies for a man called Shipley, and on 12 June 1770, he was granted a patent, which enabled him to take legal action against the Lancashire manufacturers who had begun using it. This action was withdrawn. With a partner Thomas James, Hargreaves ran a small mill in Hockley and lived in an adjacent house. The business was carried on until his death in 1778 when his wife received a payment of £400. When Samuel Crompton invented the spinning mule in c.1779 he stated he had learned to spin in 1769 on a jenny that Hargreaves had constructed.
