Hanna Parviainen (3 August 1874 Jyväskylä – 12 February 1938 Helsinki), the executive managing the family sawmills, was the first woman to become a commercial counsellor for Finland.
Parviainen worked as an accountant for her father till his death in 1900, after which she took over managing the farms owned by the family.
She inherited the plywood factory and the Säynätsalo islands in 1925 when her father and both her brothers had died.
Hanna Parviainen was afforded the title of commercial counsellor in 1926 as the first woman in Finland.
Parviainen had befriended herself with the architect Wivi Lönn, who e.g. designed an orchard in the Sulkula model farm on the shores of Lake Jyväsjärvi as well as several buildings on the Säynätsalo islands including a kindergarten and a home for the elderly.
