Charles Macintosh (29 December 1766 – 25 July 1843) was a Scottish chemist and the inventor of waterproof fabric.

The Mackintosh raincoat (the variant spelling is now standard) is named after him.
Macintosh was born in Glasgow, the son of George Macintosh and Mary Moore, and was first employed as a clerk. Macintosh married Mary Fisher in 1790, daughter of Alexander Fisher a Glasgow merchant. They had one son, George Macintosh (1791-1848).

Charles devoted his spare time to science, particularly chemistry, and before he was 20 resigned his clerkship to take-up the manufacture of chemicals. In this he was highly successful, inventing various new processes. His experiments with one of the by-products of tar, naphtha, led to his invention of waterproof fabric, the essence of his patent was the cementing of two thicknesses of cloth together with natural rubber, the rubber is made soluble by the action of the naphtha. In 1823 he was elected a fellow of the Royal Society, for his chemical discoveries.
