Murray Calder (born 15 January 1951) was a Liberal member of the House of Commons of Canada from 1993 to 2004.
Born in Mount Forest, Ontario, Calder first became a Liberal candidate in 1988, unsuccessfully contesting the Wellington—Grey—Dufferin—Simcoe electoral district.
In 2003 he served as Parliamentary Secretary to International Trade Minister Pierre Pettigrew and sat on the House of Commons Standing Committee on Foreign Affairs.
He worked with Senator Lorna Milne to campaign for public access to post 1901 Canada Census data, an issue of special interest to genealogists.
Calder has restored a number of old military vehicles as a hobby on his chicken farm in Holstein, Ontario.
