Uchan (Учан) was a Ukrainian bulletin board, founded by “Yason dinAlt”,¹⁾ that ran from November 17, 2009 to September 11, 2016. This is often considered the first²⁾ major Ukrainian imageboard, before new alternatives like Kropyvach or Fainach would eventually surpass them.

On November 17, 2009, “Yason dinAlt” establishes Uchan³⁾ on top of his 'demotivational posters' website, “demotivators.org.ua”,⁴⁾ before it was moved to “uchan.org.ua” on November 30, 2009.⁵⁾ It ran on Wakaba. After a few months, Uchan saw a surge in popularity around April 2010 which breathed life into the community, despite the later rise of alternatives like Sich and Xatach during a perceived decline.

In 2012, a brief PES tournament was held. In 2013, there was a nationalist 'anti-Russian' fervor that would explode after the 2014 coup, so it became difficult to avoid politics. During its final years, the community would expand the local Warhammer 40,000 scene, moved to its alternate “uchan.to” domain around 2015,⁶⁾ then it shut down on September 11, 2016 without warning.

• For a brief period of time, Hyperchan acquired the “uchan.org.ua” domain on April 1, 2020 and ran a spiritual successor to Uchan, dubbed 'New Uchan' (Новий Учан), but it died after two years.

• Fainach and Kropyvach - The main two successors, though the latter won out.
