Nikolai Grigorievich Chebotaryov (often spelled Chebotarov or Chebotarev, Template:Lang-ru, Template:Lang-uk) (15 June [O.S. 3 June] 1894 – 2 July 1947) was a noted Russian and Soviet mathematician. He is best known for the Chebotaryov density theorem.

He was a student of Dmitry Grave, a famous Ukrainian and Russian mathematician. Chebotaryov worked on the algebra of polynomials, in particular examining the distribution of the zeros. He also studied Galois theory and wrote an influential textbook on the subject titled Basic Galois Theory. His ideas were used by Emil Artin to prove the Artin reciprocity law He worked with his student Anatoly Dorodnov on a generalization of the quadrature of the lune, and solved a conjecture which is now known as the Chebotaryov theorem on roots of unity
