Joseph Shehyn (November 9, 1829 – July 14, 1918) was a Canadian businessman and politician.

Born in Quebec City, Quebec, the son of Edmond Sheehy and Marie (Flavie) Parent, Shehyn was raised by his maternal uncle after the death of his mother.

He later worked for the firm McCall, Shehyn and Company and would become the sole owner in 1891.

He was elected as the Liberal candidate to the Legislative Assembly of Quebec for the electoral district of Québec-Est in the 1875 election defeating Pierre-Vincent Valin.

He was summoned to the Senate of Canada for the senatorial division of The Laurentides on the advice of Prime Minister Wilfrid Laurier in 1900.
