Sir Josiah Mason (23 February 1795 – 16 June 1881) was an English industrialist, engaged in pen manufacture and other trades, and a philanthropist.

After trying his hand in his native town at shoemaking, baking, carpentering, blacksmithing, house-painting and carpet-weaving, he moved in 1816 to Birmingham.

In 1824 he set up on his own account as a manufacturer of split-rings by machinery, to which he subsequently added the making of steel pens.

Besides his steel-pen trade, Mason carried on for many years the business of electro-plating, copper-smelting, and India-rubber ring making, in conjunction with George Elkington.

This bronze bust was cast in 1951 by William Bloye from a marble statue by Francis John Williamson in 1885, which stood opposite Mason Science College in Edmund Street, but which has since been destroyed.
