Tiedonantaja is a Finnish leftist weekly newspaper. It is currently the party organ of the new Communist Party of Finland (SKP). Tiedonantaja was founded in 1968 and it served as the paper of the taistoist minority faction of the old SKP until the opposition was expelled in the mid-1980s. In the late 1980s Tiedonantaja was also the organ of the electoral front Democratic Alternative. The current editor-in-chief is Erkki Susi who was preceded by Urho Jokinen (1970–1983).
Tiedonantaja was first published irregularly by the Uusimaa district organisation of the SKP. It became statewide after other taistoist districts joined, and in 1970 the paper became weekly. In 1972 Tiedonantaja was published three times a week and from 1973 onwards, four times a week. The paper reduced back to its weekly format in 1990.
In the 1970s Tiedonantaja had circulation of about 30,000. Over 50,000 people sent May Day and new year's greetings which were published in the special editions.
