Boris Nikolaevich Delaunay or Delone (Russian: Борис Николаевич Делоне; March 15, 1890July 17, 1980) was one of the first Russian mountain climbers and a Soviet/Russian mathematician.

The spelling Delone is a straightforward transliteration from the Cyrillic alphabet. Boris Delone got his surname from an Irish ancestor called Deloney, who was among the mercenaries left in Russia after the Napoleon's invasion of 1812. Delaunay is the French transliteration of the name.

When Boris was a young boy his family spent summers in the Alps where he learned mountain climbing.[1] By 1913 he became one of the top three Russian mountain climbers. After the Russian revolution he climbed mountains in the Caucasus and Altai. One of the mountains (4300 m) near Belukha is named after him. In the 1930s he was among the first to receive a qualification of Master of mountain climbing of the USSR. Future Nobel laureate in physics Igor Tamm was his associate in setting tourist camps in the mountains.

Boris Delaunay worked in the fields of modern algebra, the geometry of numbers. He used the results of Yevgraf Fyodorov, Hermann Minkowski, Georgy Voronoy, and others in his development of modern mathematical crystallography and general mathematical model of crystals.[2] He invented what is now called Delaunay triangulation in 1934.[3] Among his best students are the mathematicians Aleksandr Aleksandrov and Igor Shafarevich.
