Rene Ernest Toupin (May 15, 1934 – March 15, 2014), born in Saint Boniface, Manitoba, was a politician in Manitoba, Canada.
Toupin was educated at Université Laval, and returned to Manitoba after his graduation. He was the Chair of the La Salle School Board from 1962 to 1966, and Chair of the La Salle Credit Union from 1962 to 1969. He was also a member of the Societe Franco-Manitobaine.
He was elected to the Manitoba legislature in the provincial election of 1969, scoring a relatively easy win in the riding of Springfield. The NDP formed a minority government following this election, and Toupin was named Minister of Consumer and Corporate Affairs on July 15, 1969. He did not seek a return to provincial politics after that time. He died on March 15, 2014, at the age of 79.
