Miles Peter Andrews (1742 – 18 July 1814) was an 18th-century English playwright, gunpowder manufacturer and politician who sat in the House of Commons from 1796 to 1814.
Andrews was the son of William Andrews, a drysalter of Watling Street and his wife Catherine Pigou. After helping his father in business in the day time, he was "accustomed to sally forth in the evening with sword and bag to Ranelagh or some other public place". He gradually made useful social connections and became a constant companion of Lord Lyttelton. He wrote plays musicals and operas. The first was performed at Drury Lane in 1774. In 1775 the opera diva Ann Cargill aged 15 ran away with him and she then had to be restrained at home by a court order. Andrews had several further plays performed at the Haymarket. Andrews lived in a mansion at Green Park where he entertained the fashionable society of London, and was a member of several clubs.
With his uncle Frederick Pigou, a director of the British East India Company, Andrews became the owner of an extensive gunpowder factory at Hawley Mills on the River Darent at Dartford, Kent. George Colman the Younger described Andrews as "one of the most persevering poetical pests", and his plays as "like his powder mills, particularly hazardous affairs, and in great danger of going off with a sudden and violent explosion". This was no idle comparison as an explosion occurred in October 1790.
In 1796 Andrews succeeded Lord Lyttleton as Member of Parliament for Bewdley which he represented until his death in 1814. There is a memorial to him in St James's Church, Piccadilly.
