Richard Royce Schrock (born 4 January 1945) is an American chemist and Nobel laureate recognized for his contributions to the metathesis reaction used in organic chemistry. In 2005, Schrock received the Nobel Prize in Chemistry, with Robert H. Grubbs and Yves Chauvin, for his work in the area of olefin metathesis, an organic synthesis technique.

He holds a B.A. (1967) from the University of California, Riverside and a Ph. D. (1971) from Harvard University.
In 1971-72, he carried out postdoctoral studies at the University of Cambridge with Lord Jack Lewis.

He joined the faculty of the Massachusetts Institute of Technology in 1975 and became full professor in 1980.
He has held his current post, the Frederick G. Keyes Professor of Chemistry, at MIT since 1989.
Schrock is a member of the American Academy of Arts and Sciences, National Academy of Sciences and was elected to the Board of Overseers of Harvard University in 2007.
