George "G." Michael Bancroft, OC FRSC, (born 1942) is a Canadian chemist and emeritus professor at the University of Western Ontario.

[3] Over a 20-year period Bancroft would become one of the world's leading experts in Mössbauer spectroscopy, publishing more than 80 papers, a major review and an authoritative textbook in the field.

He began work at the Synchrotron Radiation Center (SRC) at the University of Wisconsin-Madison, US, in 1975, as a result of contact established with then-SRC director Ed Rowe at the 1972 meeting.

After several failed attempts were made to establish a synchrotron facility in Canada, Bancroft submitted a proposal to the NRC to build a Canadian beamline at SRC.

In 1994 NSERC recommended building a Canadian synchrotron, and set up a committee to decide between two rival bids to host the facility, led by Dennis Skopik of the University of Saskatchewan and Bancroft of UWO.
