Tahvo Putkonen (30 October 1795 in Suonenjoki, Finland – 8 July 1825 in Pieksämäki) was a Finnish farmhand, who killed tenant farmer Lasse Hirvonen on 26 December 1822 during the Finnish grand duchy period in Pieksämäki. He was sentenced to death on 30 July 1823. He made numerous appeals all the way to the Emperor, but was each time denied pardon. On 8 July 1825 Putkonen was beheaded, and his execution is believed to be the last example of capital punishment in Finland during peacetime.
