Joseph Arthur Roméo Desfossés (November 3, 1897 – April 1, 1980) was a provincial politician from Alberta, Canada. He served as a member of the Legislative Assembly of Alberta from 1951 to 1959 sitting with the Liberal caucus in opposition.
Desfosses ran for a seat to the Alberta Legislature in a by-election held on June 21, 1951, in the Grouard electoral district. He defeated two other candidates in a hotly contested race on second vote preferences to pick up the seat for the provincial Liberals.[1]
Just over a year later Defosses ran for a second term in office in the 1952 Alberta general election. He held the district winning a small plurality on the first vote count, and hanging to win the three-way race on the second vote count by 150 votes.[2]
Defosses ran for a third term in the 1955 Alberta general election. He won a larger popular vote, but was unable to secure a majority. On the second vote count Defossess easily held his seat defeating two other candidates.[3]
Defosses retired from the legislature at dissolution of the assembly in 1959.
