Marcin Knackfus was a Polish–Lithuanian Neoclassical architect of German descent. Born near Warsaw, he worked in the Grand Duchy of Lithuania and particularly in its capital Vilnius. He was a tutor of Laurynas Gucevičius.
Knackfus was influenced by other Polish–German architects of late Baroque and early Neoclassicism. He moved to Vilnius around 1768.
