Henry Miles, FRS (2 June 1698 – 10 February 1763) was an English Dissenting minister and scientific writer; a Fellow of the Royal Society known for experiments on electricity.
He held the double appointment till 1744, and for the rest of his life was minister at Tooting only, having John Beesley as his assistant from 1756.
To his pulpit work, for thirty years, he devoted two days a week, rising between two and three in the morning to write his sermons.
His widow, Emma Miles (died 1790), by deeds of 6 October 1763 and 15 February 1766, settled an endowment of £500 on the ministry at Tooting, and conveyed the meeting-house to trustees for the use of Dissenters of "the presbyterian or independent denomination."
His communications to the Philosophical Transactions extend from 1741 to 1753, and relate to natural history, meteorology, and electricity, in which he made new experiments.
