Italian inventions and discoveries are objects, processes or techniques invented, innovated or discovered, partially or entirely, by Italians.

Italian people – living in the Italic peninsula or abroad – have been throughout history the source of important inventions and innovations in the fields of writing, calendar, mechanical and civil engineering, musical notation, celestial observation, perspective, warfare, long distance communication, storage and production of energy, modern medicine, polymerization and information technology.

Italians also contributed in theorizing civil law, scientific method (particularly in the fields of physics and astronomy), double-entry bookkeeping, mathematical algebra and analysis, classical and celestial mechanics. Often, things discovered for the first time are also called inventions and in many cases, there is no clear line between the two.

The following is a list of inventions, innovations or discoveries known or generally recognized to be Italian.

Alphabetical list of Italian Inventions

A Roman acqueduct: Romans constructed aqueducts throughout the Republic and later Empire, to bring water from outside sources into cities and towns. Aircraft with tractor configuration propeller: the world's first airplane having a "Tractor" configuration, propeller on the front, was the Goupy No.2 (first flight on 11 March 1909) designed by Mario Calderara and financed by Ambroise Goupy at the French firm Blériot Aéronautique.Mario Calderara, Commander Calderara Glances Backward and Ahead, U.S. Air Services, Volume 15, Air Service Publishing Company, September 1930, page 38 At the time, it was the fastest airplane in existence. Later, this solution became the most common type of biplane used in the First World War. Amici prism: invented by Giovan Battista Amici Amici roof prism: invented by Giovan Battista AmiciRonchi, Vasco (1970). "Amici, Giovan Battista". Dictionary of Scientific Biography. 1. New York: Charles Scribner's Sons. pp. 135-137. . Anatomical theatre: used for teaching anatomy in early modern universities; the first one being at the university of Padova (1595).

Dipped candle: Romans made candles using rendered animal fat (called tallow), beginning around 500 BC. Caprotti valve gear: a valve design that found significant application in steam locomotives. Carbon paper, invented by Pellegrino Turri in 1806Adler, Michael H. (1973) The writing machine (London: George Allen & Unwin Ltd.) Casino: the first public, legal and government-owned casino was a Venetian four-story gambling house called "Ridotto", opened in 1638. Julian calendar: later perfected by Luigi Lilio becoming the Gregorian calendar, which is today's internationally accepted civil calendar, also known as the Western or Christian calendar. Cardan suspension of a gimbal: named after the Italian inventor Gerolamo Cardano (1501–1576), who described the device in detail. This device made inertial navigation possible. Cello: with 'The King Violoncello' by Andrea Amati being the earliest known bass instrument of the violin family to survive. Centrifugal Pump: the first machine that could be characterized as a centrifugal pump was a mud lifting machine that appeared as early as 1475 in a treatise by the Italian Renaissance engineer Francesco di Giorgio Martini. Codex: is the precursor of modern books, having defined the reference format of virtually all the books of Western civilization. Invented during Roman times, its adoption was later spread by Christianity.Roberts, Colin H; Skeat, TC (1983). The Birth of the Codex. London: British Academy. pp. 15–22. . (Modern Diesel) Common Rail: designed by researcher Mario Ricco of the FIAT Group. Proportional compass: generally featuring a proportional scale, it could be used for calculus of infinitesimals and proportions of geometric figures. There are three types: Reduction compass: developed by Commandino Federico (inventor of the polymetric compass) and Joost Bürgi. Proportional eight spikes compass: invented by Fabrizio Mordente and used by G. Bruno in his research of the physical minimum. Flat hands compass: such as Galilei's one. Roman concrete: for edification purposes, more resilient than modern concrete. Confetti: initially meaning a type of sweet, then used for analogy to indicate little chalk balls used in Italy during carnival festivities. Mangilli di Crescenzago (Milan) is credited as an early inventor of paper confetti. Connecting rod: a device invented by Roman engineers to transform circular motion into linear motion. Corvus: Roman naval boarding device. Composite order: Imperial Roman form of the Corinthian order. Cruise ship: The Kingdom of the Two Sicilies — whose territory today corresponds to much of southern Italy, historically a key destination of the Grand Tour — offered what is considered the first cruise in history aboard the Francesco I. Built in 1831, the Francesco I departed from Naples in early June 1833, following a dedicated advertising campaign. Nobles, officials, and royal princes from across Europe boarded the vessel, which over the course of a little more than three months sailed to Taormina, Catania, Syracuse, Malta, Corfu, Patras, Delphi, Zante, Athens, Smyrna, and Constantinople, providing passengers with excursions and guided tours.

D Dental fillings: First mentioned by Cornelius Celsus in the 1st century AD. Dentures: the first dentures were developed by the Etruscans in 700 BCThe inventions that changed the world, Reader's Digest (1982) [Portuguese edition of 1983] Di Pietro air engine: a pneumatic engine built by Angelo Di Pietro, which require very low pressure to start rotation. This engine produces almost no vibration, internal wear or friction and is potentially useful for a wide range of environment-friendly applications. In 2004, it has 100% more efficiency than any other air engine to that date. It also represents the first air engine that could be applied in transportation. Dipleidoscope: invented by Giovan Battista Amici.Ronchi, Vasco (1970). "Amici, Giovan Battista". Dictionary of Scientific Biography. New York: Charles Scribner's Sons. . Dollying: to move a camera on a dolly, esp. toward or away from the subject being filmed or televised. Giovanni Pastrone first used this method in 1914. Doppio Borgato: a musical instrument which is a variation of the pianoLarry E. Ashley, Pierce Piano Atlas, 12th edition, Larry E. Ashley Publisher, Albuquerque, NM U.S.A., 2008, p.58. Double-entry bookkeeping system (for accounting): developed in the mercantile city-states of medieval Italy and first documented by Lucas de Burgo in Venice. Perfected by Amatino Mannucci in the 14th century. The actual invention could have been Roman or Asiatic. Anyway, the system reached a huge diffusion as a consequence of Italian use and theorisation, with Summa de Arithmetica containing the rules of double-entry, the first example of calculating a neperian logarithm as well as early examples of probability calculus. Doxorubicin: a chemotherapy agent invented by Farmitalia Spa in the 1950s. D-Shape: a new 3D printer capable of printing entire buildings invented in 2004 by Enrico Dini.

Eau de Cologne: perfume developed by Johann Maria Farina in 1709.Wells, Frederick V.; Billot, Marcel (1981). Perfumery Technology. Art, science, industry. Chichester: Horwood Books. pp. 25, 278. Electroplating: a manufacturing technique invented by Luigi Valentino Brugnatelli in 1805.Mohler, James B. (1969). Electroplating and Related Processes. Chemical Publishing Co. . He pioneered galvanoplastic experiments, introducing the technique of electroplating. His acquaintance with A. Volta played an important role in his scientific career. He hypothesized that in the chemical pile there was also a transport of atoms, obtaining experimental evidence of this. He discovered the properties of coal cathodes as electrical conductors and succeeded in covering them with a metallic layer. He sensed the possible applications in the industrial field, sharing this procedure with a Pavese goldsmith, who used it. Encyclopedia: from the Greek enkýklios paidèia, meaning a set of doctrines constituting a complete education. The comprehensive works of Aristotle can be considered encyclopedic (covering politics, rhetoric, ethic, aesthetic, psychology, biology, math). The first Latin encyclopedia was written by Cato the Elder in an attempt to mitigate the influence of Greek culture. He wrote for his son an "encyclopedia" of what he believed to be the necessary subjects for the Roman citizen: agriculture, rhetoric, medicine, law and warfare. Marcus T. Varro wrote a second, more complete and systematic encyclopedia, covering nine disciplines: grammar, rhetoric, logic, arithmetic, geometry, astronomy, musical theory, medicine, and architecture. Plinius the Elder wrote Historia naturalis, the first encyclopedia to survive as a complete work. Marziano F. Capella wrote an allegoric encyclopedia in prose and verses, De nuptiis Mercurii et Philologiae. These encyclopedias, along with the works of Cassiodorus and Boethius, paved the way for the medieval seven liberal arts. Epidemiology (innovated): Roman scholar Marcus Varro mentioned microorganisms as a possible causal agent of diseases. Girolamo Fracastoro, in the mid 16th century, was the first one to scientifically state the real nature of germs, infection, and contagious ways of disease transmission. He attributed the causes of diseases to very small living particles, invisible to the eye. They were considered vulnerable to fire, capable of self multiplying as well as spreading by air.On Contagion, Contagious Diseases and Their Cure (1546) by Girolamo Fracastoro (1478-1553) Espresso machine: first prototype invented by Angelo Moriondo in 1884 in Turin."Bollettino delle privative industriali del Regno d'Italia", 2nd Series, Volume 15, Year 1884, pages 635 – 655 (piston driven model) invented by Achille Gaggia in 1945.Pendergrast, Mark (2001) .
