John Imbrie (born July 4, 1925) is an American Paleoceanographer.

Imbrie received a Ph.D. from Yale University in 1951. He was the recipient of a MacArthur Fellowship in 1981. He was awarded the William H. Twenhofel Medal by the Society for Sedimentary Geology in 1991. Imbrie has been on the faculty of the Geological Sciences Department at Brown University since 1977 [ [http://www.eng.yale.edu/content/AlumniHAC_person.asp?HAC_IK=63 Yale Science and Engineering Alumni Hall of Achievement web page, accessed April 9, 2008] ] , where he has held the Henry L.

Imbrie is probably best known as a co-author of the "Hays, Imbrie and Shackleton" paper in Science [cite journal

Using ocean sediment cores, the Science paper verified the theories of Milutin Milanković that oscillations in climate over the past few million years could be correlated with Earth's orbital variations of eccentricity, axial tilt, and precession around the Sun (see Milankovitch cycles).
