Raivaaja (English: The Pioneer) was a Finnish-language newspaper published from 1905 to 2009 in Fitchburg, Massachusetts, by Raivaaja Publishing Company. For the first three decades of its existence the publication was closely associated with the Socialist Party of America (SPA). In 1936 as part of a large factional split in the SPA, the former Finnish Socialist Federation severed its connection to become the "Finnish American League for Democracy," with Raivaaja remaining the official organ of this remodeled organization.
