Jack Reimer is a Progressive Conservative politician in Manitoba, Canada. He served in the cabinet of Premier Gary Filmon, and is a current member of the opposition in the Manitoba legislature.

Reimer has a Degree in Sociology from the University of North Dakota. Before entering politics, he was a Marketing and Management Instructor for Imperial Oil, and worked in the automobile and tourism industries in Manitoba. He also owned a restaurant and service station. Reimer has received a Mayor's Award for Leadership and Service to the Winnipeg Community, as well as a Certificate of Merit from the government of Canada.

Reimer was first elected to the Manitoba legislature in the 1990 general election, defeating Liberal candidate Linda Asper in the southeastern Winnipeg riding of Niakwa, 4950 votes to 4301. He was re-elected by a wider margin in the 1995 election, in a period when provincial Liberal fortunes were on the decline (the New Democratic Party does not have a strong historical presence in this section of Winnipeg).

On May 9, 1995, Reimer was appointed Minister of Urban Affairs and Minister of Housing in Gary Filmon's government. He retained these portfolios until the Progressive Conservative government was defeated in 1999. Reimer himself was easily re-elected in the 1999 election, defeating his NDP opponent by over 2500 votes in the renamed Southdale riding.

The NDP made some historic breakthroughs in southern Winnipeg in the 2003 election, but Reimer was nonetheless re-elected over his NDP opponent, Carolyn Frost , by over 1,000 votes. Now a member of the opposition, he continues to hold a number of critic portfolios in the legislature.

Reimer has recently opposed efforts by the Manitoba government to provide safe injection paraphernalia to drug addicts, arguing instead for a zero-tolerance policy in such matters. He has also criticized the expansion of a casino economy in the province.
