Augusta Eleonora "Elin" Engström (1860–1957) was a Swedish politician (Social Democrat) and trade unionist.
In 1878, she married the Cooper (profession) and trade unionist Jöns Engström.
She supported herself with several temporary jobs such as writing letters on behalf of others, washing clothes and babysitting, but was still forced to place two of her children in an orphanage: at that time, it was common for poor parents to place their children in orphanages temporarily for economic reasons, and take them back when they could afford to take care of them.
From 1886 to her retirement in 1935, she worked as an office clerk on the Social Democratic newspaper and organ Social-Demokraten.
She was a member of Kommittén för den kvinnliga agitationen (Committee of Female Agitation) in 1900–1901, member of Socialdemokratiska kvinnokongressen (Social Democratic Women's Congress) in 1908–1914, accountant of the Socialdemokratiska kvinnokongressen in 1914–1920, accountant of the Social Democratic Women in Sweden in 1920–1936, board member of the Communal Retirement Board of Stockholm 1917–1935, and board member of the Communal Housing Board of Stockholm in 1917–1923.
