The Finnish Wikipedia (Finnish: Suomenkielinen Wikipedia) is the edition of Wikipedia in the Finnish language. With 622,932 articles, it is currently the 29th-largest Wikipedia and the largest Wikipedia in a Uralic language. Wikipedia is the only encyclopedia in Finnish which is still updated.[1]

The Finnish language project was started on 9 September 2002, but it remained at a very primitive stage until well into 2003. The speed of development picked up somewhat after the MediaWiki software was upgraded to Phase III in late November 2003, and continued to increase steadily through 2004.

In 2013, the reliability of the Finnish Wikipedia was investigated by the newspaper Helsingin Sanomat. The researchers used experts to evaluate quality of randomly selected 134 articles and found that 70% of the articles scored well for accuracy.[1][2]

In 2026, Finnish Wikipedia contributors received the State Award for Public Information for "their long-term and communal work in building and maintaining open knowledge" on Finnish Wikipedia as well as on Swedish, Inari Sámi and Northern Sámi Wikipedias. The prize of €20,000 was presented to Wikimedia Suomi, a local Wikimedia chapter.[3][4]
