Eisenhammer Dorfchemnitz is an historic hammer mill in Dorfchemnitz in the Ore Mountains of Germany. The mill is an important witness to proto-industrial development in the Ore Mountains. Of the once-numerous hammer mills only three others remain working in Saxony apart from the Frohnauer Hammer: the Frohnauer Hammer Mill, the Grünthal Copper Hammer Mill and the Freibergsdorf Hammer Mill. The mill, which is situated on the Chemnitzbach stream, has been a technology museum since 1969 which, in addition to the actual hammer mill, also has a local history room.
