Aino Maria Kuusinen (née Turtiainen, subsequently Sarola; 5 March 1886 – 1 September 1970) was a Finnish Communist who worked for Comintern around the world in the 1930s, and was imprisoned in the gulag before she escaped to the West.

Upon graduation, on 9 July 1909, Kuusinen married Leo Sarola, who worked as an engineer at the Railway Administration.

Kuusinen was then secretly in Finland and his friends stayed for a few nights with Leo and Aino Sarola.

Kuusinen left Finland in the spring of 1920 to Sweden, where he lived for some time and began sending letters to Aino.

In 1965, Aino Kuusinen traveled to Finland and from there to Italy, where she wrote her memoirs, ordering them to be published only after her death.
