Matthew Piers Watt Boulton of Tew Park and Haseley Court, also believed to have been published additionally under the pseudonym M.P.W. Bolton (22 September 1820 – 30 June 1894), was a British classicist, elected member of the UK's Metaphysical Society, an amateur scientist and an inventor, best known for his invention of the aileron, a primary aeronautical flight control device. He patented the aileron in 1868, some 36 years before it was first employed in manned flight by Robert Esnault-Pelterie in 1904.

Boulton was the son of Matthew Robinson Boulton, and as well the grandson of Matthew Boulton, who founded the Soho Manufactory and the Soho Mint. His grandfather also co-founded the Soho Foundry with James Watt, which employed steam engines of the latter's design. Born into a family of significant wealth and means, M.P.W. was broadly educated in the classics, philosophy and sciences, subsequently becoming well versed in steam engine design, and then transferring his interest to the basic conceptual designs of jet propulsion and rocket motors. However, whatever personal interest he held in the foundry's operation and the coinage mint he inherited from his father soon waned, and he subsequently closed and sold the mint facility in 1850. Thereafter he conducted numerous studies, wrote a wide variety of papers and earned a number of patents, including for an aileron flight control system, various types of motive power engines and their components such as propellers and pumps, plus other works on solar heat, photography and more.
