John Browne or Brown (died 1735) was an English chemist, elected Fellow of the Royal Society in 1721.[1]

His father John Browne of London was an apothecary, and Browne joined the Society of Apothecaries in 1697. He discovered the presence of magnesia in sea-water, and researched the manufacture of Prussian blue (invented by Johann Jacob Diesbach, in 1706[2]), publishing on these topics in the Philosophical Transactions.[1][3]
