Joel Spencer (born April 20, 1946) is an American mathematician. He is a combinatorialist who has worked on probabilistic methods in combinatorics and on Ramsey theory. He received his doctorate from Harvard University in 1970, under the supervision of Andrew Gleason.[1] He is currently (as of 2018) a professor at the Courant Institute of Mathematical Sciences of New York University. Spencer's work was heavily influenced by Paul Erdős, with whom he coauthored many papers (giving him an Erdős number of 1).

In 1963, while studying at the Massachusetts Institute of Technology, Spencer became a Putnam Fellow.[2] In 1984 Spencer received a Lester R. Ford Award.[3] He was an Erdős Lecturer at Hebrew University of Jerusalem in 2001. In 2012 he became a fellow of the American Mathematical Society.[4] He was elected as a fellow of the Society for Industrial and Applied Mathematics in 2017, "for contributions to discrete mathematics and theory of computing, particularly random graphs and networks, Ramsey theory, logic, and randomized algorithms".[5] In 2021 he received the Leroy P. Steele Prize for Mathematical Exposition with his coauthor Noga Alon for their book The Probabilistic Method.[6]
