Kasper (Gaspar) Tochman (1797 – December 20, 1880) was a Polish-born American lawyer and soldier who formed the Polish Brigade (14th and 15th Louisiana regiments) of Johnson's Division.

Vicechairman of the Polish Patriotic Society, he was a good friend of the Commander-in-Chief of the November Uprising Jan Zygmunt Skrzynecki as well as Joachim Lelewel and Maurycy Mochnacki.

An account published by the Baltimore Sun described him as a patriot of high reputation who was capable of "thrilling bursts of eloquence".

Tochman tried both to integrate the Polish community - by establishing the Polish-Slavonic Literary Society which gathered also many Americans - as well as sought contact with prominent US officials; his house in Virginia was visited by Abraham Lincoln, William Seward or Samuel Tilden among others.

After the defeat of the Confederacy, Tochman was nominated Virginia Immigration Commissary gathering people to settle in the state.
