Jonas Vilčinskas, also known by his codenames Algirdas and Svajūnas (23 February 1930 – 19 September 1953) was an anti-Soviet Lithuanian partisan and the last commander of their Kęstutis military district.

He graduated from the Jurbarkas gymnasium in 1948[1] and attempted to achieve higher education, however as the son of a kulak he was unsuccessful in doing so.

He intended to reach the Supreme Committee for the Liberation of Lithuania (VLIK) and establish contacts with communication points abroad.

However, these plans were stalled as a partisan by the name of Klemensas Širvis, who helped establish contact between Vilčinskas and Žemaitis, was found to be already recruited by Soviet agents.

[4] Jonas Vilčinskas was eventually lured in the town of Antanava of the Raseiniai district[4] by Soviet agents and recruited former partisans to a false meeting, and then on 19 September 1953 he was shot.
