Ukrainian Wikipedia

The Ukrainian Wikipedia (Ukrainian: Українська Вікіпедія, romanized: Ukrajinska Vikipedija) is the Ukrainian language edition of the free online encyclopedia, Wikipedia. The first article was written on 30 January 2004. As of November 2025,^[update] the Ukrainian Wikipedia has 1,397,243 articles and is the 14th largest Wikipedia edition.

As of November 2022,^[update] it is the second most visited language Wikipedia in Ukraine, with 90 million page views, behind the Russian Wikipedia, at 100 million page views. There is a long-term trend for the Ukrainian language edition to be increasingly favored in comparison to the historically dominant Russian language edition.

In the Ukrainian Wikipedia, the subject of mining has been covered to an greater extent than all other Wikipedias, due to the considerable contribution by one person, Volodymyr Biletsky, a professor at Donetsk National Technical University. Using the Mining Encyclopedia, Biletsky has contributed over 10,000 articles on the subject to Ukrainian Wikipedia. In 2013, the Institute of History of Ukraine at the National Academy of Science gave permission to the Ukrainian Wikipedia to use the digital version of the Encyclopedia of History of Ukraine that was published online. The Higher School Academy of Science and Forest Engineering also allowed Wikipedia to freely use their information resources.

Generally, before the 2014 Maidan Revolution, Ukrainian Wikipedia hold approximately the 10 to 20 percent of the pageviews from Ukraine, depending on the season and steadily growing, reaching for first time a share of above 20% in late 2013. The success of Euromaidan and the subsequent improvement in Ukrainian language's status have positively impacted the reach of Ukrainian Wikipedia.

One of the areas where activity is notable is in Wiki Loves Monuments project, an annual international photo contest focused on cultural and historical monuments. Ukrainian Wikipedians were ranked 4th among 36 participating countries for the number of uploads of images as part of this project in 2012. In 2014, Ukrainian Wikipedians were the winners of the contest that year.

As of May 2023,^[update] the Ukrainian Wikipedia is the second most popular Wikipedia in Ukraine, slightly below Russian, despite that both language versions have more than a million articles. This is attributed to the historic bilingualism in Ukraine, the Russification of Ukraine and the Ukrainian language during the Tsarist and Soviet era, and the popularity of Russian-language content in present-day Ukraine. However, the popularity of Ukrainian Wikipedia in Ukraine is increasing every year, compared to the Russian version.

In January 2016, the ratio of Russian to Ukrainian Wikipedia use was 4.6 times, decreasing to 2.6 times in January 2019, 2.4 times in January 2020, and 2 times in January 2021. Extrapolation shows that in 2025, in Ukraine, the popularity of the Ukrainian Wikipedia will be higher than the popularity of the Russian Wikipedia.

Since the Russian invasion of Ukraine, the difference between the two languages has further decreased, and in October 2022 it was just ten million pageviews (100 million pageviews for Russian in Ukraine and 90 million pageviews for Ukrainian), the lowest ever recorded. Due to the fact that many students consult Ukrainian Wikipedia for information about the literature works, the writers and other parts of the school curriculum, the pageviews of Ukrainian Wikipedia are generally halving during the summer. This trend is observed in many other Wikipedias of the former Soviet space, including Kazakh and Uzbek ones. The impact of this trend tends however to decrease as of 2023. In July 2023 Ukrainian had 61 million pageviews and Russian 87 million pageviews in Ukraine which is lesser than half of the difference 72 million pageviews (112 to 40) in July 2021.
