Edmund Murton Walker (October 5, 1877 – February 14, 1969) was a Canadian entomologist.

He noted the peculiar characters but considered it a primitive lineage of orthopterans, and many of his later researches were on the analysis of trends within the Orthoptera.

[2][3][4][5][6][7] Another area of work was on the fly Wohlfahrtia vigil and its involvement in cutaneous myiasis in humans.

[1] Walker founded the invertebrate collection at the Royal Ontario Museum (which his father had helped create) in 1914, and served in various directorships at the museum: as Assistant Director 1918–1931, and as Honorary Director 1931–1969.

Walker also published the three volume Odonata of Canada and Alaska, considered a definitive work on the topic, and was editor of The Canadian Entomologist from 1910 when he succeeded C.J.S.
