SS Champlain was a cabin class ocean liner built in 1932 for the French Line by Chantiers et Ateliers de Saint-Nazaire, Penhoët.

Although not as well remembered as her larger fleetmates, the Champlain was the first modern ocean liner and embodied many design features later incorporated into the French Line's SS Normandie.

Her interiors were designed by René Prou who decorated spaces on several earlier French Line ships, including the cabin motorship SS Lafayette [fr].

At the outbreak of the Second World War, the Champlain was pressed into evacuee work, transporting refugees from Europe to the safety of North America.

On 17 June 1940, the liner struck a German air-laid mine while swinging at anchor in the waters off La Pallice, France, near Île de Ré, and quickly heeled over on her side.
