The Finnish Wikipedia (Finnish: Suomenkielinen Wikipedia) is the edition of Wikipedia in the Finnish language. By article count, it is the 24th largest Wikipedia with about 474,000 articles as of January 2020. Wikipedia is the only encyclopedia in Finnish which is still updated. The Finnish language project was started in late 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. Despite the small number of native Finnish speakers and the high number of Finnish speakers who are also fluent in English, the Finnish Wikipedia is currently the 22nd largest Wikipedia with over 250,000 articles. The ratio of Finnish language Wikipedia articles to the number of Finnish speakers is the 16th-largest at 94.6 articles per 1000 speakers. These figures were based on Ethnologue's estimate of 5,009,390 Finnish-speakers. 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.
