Blain Kevin Morin (born September 30, 1960) is a former politician in Ontario, Canada. He was a New Democratic member of the Legislative Assembly of Ontario from 1998 to 1999 who was elected in a by-election. He represented the riding of Nickel Belt in the Sudbury, Ontario, area.

Morin was president of the Canadian Union of Public Employees, Sudbury district.^[1] He subsequently worked for the Ontario Federation of Labour.

Morin ran in a by-election to replace Floyd Laughren, who had retired in 1998. He was elected to the legislature in a by-election on October 1, 1998, defeating Progressive Conservative candidate Gerry Courtemanche by 1,364 votes.^[2]

In 1999, the provincial ridings of Nickel Belt and Sudbury East were merged for the 1999 provincial election; even during the by-election campaign, Morin was already indicating that he did not intend to compete against Sudbury East's popular incumbent Shelley Martel for the merged riding's nomination.^[2] There was some consideration that he might run for the NDP nomination in the neighbouring riding of Sudbury instead, but he did not do so.^[2]

After leaving the legislature in 1999, Morin went back to work for CUPE as a health and safety representative.^[3]
