Elijah Harper was a Canadian Oji-Cree politician who served as a member of the Legislative Assembly of Manitoba (MLA) from 1981 to 1992 and a member of Parliament (MP) from 1993 to 1997. Harper was elected chief of the Red Sucker Lake Indian Band in 1978, serving for four years and worked as a policy analyst prior to entering politics. He was a key factor in the rejection of the Meech Lake Accord, a proposed amendment of the Canadian constitution.

The Meech Lake Accord was a series of proposed amendments to the Constitution of Canada negotiated in 1987 by Prime Minister Brian Mulroney and all 10 Canadian provincial premiers. It was intended to persuade the government of Quebec to symbolically endorse the 1982 constitutional amendments by providing for some decentralization of the Canadian federation.
