The Leonard G. Berry Medal is an annual award of the Mineralogical Association of Canada. Established in 1987, it is named after Leonard G. Berry (1914–1982), a Canadian geologist who made notable contributions to mineralogy and who was a founding member of the Association. The award is granted for important contributions to mineral science in Canada or for significant long-term service to the Mineralogical Association of Canada. The medalist is chosen by a committee which includes two past recipients.
