James Glen Cummings (born April 12, 1944) is a farmer and former politician in Manitoba, Canada. He was a member of the Legislative Assembly of Manitoba from 1986 to 2007, and was as a cabinet minister in the government of Gary Filmon.
The son of James William Cummings and Lillian Grace McDonald, he was born in Neepawa, Manitoba, and was educated at Neepawa Area College. Before entering provincial politics, he was a school board chair and trustee in the Beautiful Plains School Division, and worked as a farmer. He also sat on the executive of the Beautiful Plains Agricultural Society for twelve years. In 1969, he married Heather Lynne Harvey.
In the provincial election of 1986, Cummings was elected as a Progressive Conservative in the rural riding of Ste. Rose, defeating New Democrat Gary Anderson by 3735 votes to 3020. The NDP won the election, and Cummings became a member of the parliamentary opposition.
The Progressive Conservatives won the provincial election of 1988, and Cummings was re-elected in Ste. Rose by an increased margin (with the Liberals overtaking the NDP for second place). When Gary Filmon was sworn in as Manitoba's Premier on May 9, 1988, Cummings became Deputy Premier and Minister of Municipal Affairs with responsibility for administration of the Manitoba Public Insurance Corporation Act and the Jobs Fund Act. On April 21, 1989, he was shifted out of Municipal Affairs and was made Minister of the Environment, while retaining his other positions.
Cummings was easily re-elected in the provincial election of 1990, in which the Progressive Conservatives won a majority of seats. He was removed as Deputy Premier on February 5, 1991, while retaining his other positions. In the provincial election of 1995, he defeated NDP candidate John Morrisseau by 3762 votes to 2341.
