The year 1859 in science and technology involved some significant events, listed below.

Archaeology

• May 26 & June 2 – Geologist Joseph Prestwich and amateur archaeologist John Evans report (to the Royal Society and Society of Antiquaries of London, respectively) the results of their investigations of gravel-pits in the Somme valley and elsewhere, extending human history back to what will become known as the Paleolithic Era.

Astronomy

• August 28–September 2 – The solar storm of 1859, the largest geomagnetic solar storm on record, causes the Northern lights aurora to be visible as far south as Cuba and knocks out telegraph communication. This is also called the Carrington event, Richard Carrington being the first known person to observe solar flares, due to this storm. It is also the first major solar radiation storm to be recorded.
• Marian Albertovich Kowalski publishes the first usable method to deduce the rotation of the Milky Way.
• Attempting to explain Mercury's solar orbit, French mathematician Urbain Le Verrier proposes the existence of a hypothetical planet, Vulcan, inside its orbit and amateur astronomer Edmond Modeste Lescarbault claims to have observed it during March.

Biology

• March 21 – The Commonwealth of Pennsylvania issues the charter establishing the Zoological Society of Philadelphia, the first organization of its kind in the United States and founder of the nation's first zoo.
• November 3 – Alfred Russel Wallace's paper "On the Zoological geography of the Malay Archipelago", introducing the Wallace Line, is read by Charles Darwin to the Linnean Society of London.
• November 24 – Charles Darwin publishes On the Origin of Species.
• December – Joseph Dalton Hooker's Introductory Essay to the Flora Tasmaniae supports Darwin's theories.
• Isidore Geoffroy Saint-Hilaire, in the second volume of Histoire naturelle générale des Règnes organiques, introduces the term ethology.
• Rudolf Virchow publishes Vorlesungen über Cellularpathologie in ihrer Begründung auf physiologischer und pathologischer Gewebelehre, a major textbook on cellular pathology.

Chemistry

• Benjamin Collins Brodie reports the highly lamellar structure of thermally reduced graphite oxide.
• Aleksandr Butlerov discovers hexamine.
• August von Hofmann isolates sorbic acid.
• Gustav Robert Kirchhoff and Robert Bunsen invent an improved spectroscope.

Climatology

• John Tyndall discovers that some gases block infrared radiation. He suggests that changes in the concentration of these gases could bring climate change.

Geography

• The Royal Geographical Society of London is granted a Royal Charter by Queen Victoria.

Mathematics

• Arthur Cayley produces the first Cayley–Klein metric.
• Bernhard Riemann publishes his paper on number theory, Ueber die Anzahl der Primzahlen unter einer gegebenen Grösse ("On the Number of Primes Less Than a Given Magnitude") including the Riemann zeta function and Riemann hypothesis.

Medicine

• Florence Nightingale publishes Notes on Nursing: What it is and What it is Not in London.
• District nursing begins in Liverpool, England, when philanthropist William Rathbone employs Mary Robinson to nurse the sick poor in their own homes.

Technology
