DMG Mori Seiki Co., Ltd. (formerly Mori Seiki Co., Ltd (株式会社森精機製作所[1] Kabushiki Kaisha Mori Seiki Seisakusho?)) (TYO: 6141) is a Japan-based company, headquartered in Nakamura-ku, Nagoya, engaged primarily in the manufacture and sale of machine tools. Since its establishment in 1948, it has grown into one of the largest machine tool builders in the world. With its sister company in Germany, DMG Mori Seiki AG, it markets machine tools worldwide under the brand DMG Mori.

Circa 2009, Japan's Mori Seiki entered into a strategic partnership with Germany's Deckel-Maho-Gildemeister (DMG) of Gildemeister AG, yielding the current two DMG Mori Seiki organizations.
