Francis Daniel Johnson Sr. PC (April 9, 1915 – September 26, 1968) was a Canadian politician and the 20th premier of Quebec from 1966 to his death in 1968.

He was the son of Francis Johnson, an anglophone labourer of Irish heritage, and Marie-Adéline Daniel, a French Canadian.

Under the same slogan, Égalité ou indépendance, his party won the 1966 election and he became Premier of Quebec, a position that he retained until his death.

Among the guests were Johnson, his predecessor, Jean Lesage, and René Lévesque, the former Hydraulic Resources minister responsible for the consolidation of all investor-owned utilities into Hydro-Québec in 1962 to 1963.

Photographs taken at the banquet show the three men were in excellent spirits, holding hands, and smiling,[5] but relations between the Liberal leader and his former cabinet minister were strained by Lévesque's recent defection to the Mouvement Souveraineté-Association, a precursor of the Parti Québécois.
