William Farrington (died 1659) was an English politician who sat in the House of Commons in 1640.
His grandfather left him the estate at Worden in 1610, cutting out his father who was said to have been a spendthrift.
[3] In the Civil War, he was appointed a commissioner of array, reported by the Parliamentarians as one of "the most busy and active" and made colonel of the newly raised Lancashire Militia.
In 1642 his servant, William Sumner, captured a stock of gunpowder at Preston and Farrington accompanied Lord Strange to the siege of Manchester.
He was succeeded by his eldest son William who also fought in the Royalist cause and was awarded the title of Knight of the Royal Oak.
