ČKD (Českomoravská Kolben-Daněk) (Czech pronunciation: [tʃɛskoˈmorafskaː kolˈbɛn daˈɲɛk]) was one of the largest engineering companies in the former Czechoslovakia and today's Czech Republic.

ČKD was formed in 1927 from the merger of two smaller companies, Českomoravská-Kolben (founded 1896, produced machinery for hydro dams) and Breitfeld-Daněk (founded 1854, produced machinery for mines and food industry).

From 1927 until 1929 ČKD's products included a motorcycle designed by Jaroslav František Koch. It was an advanced four-stroke single-cylinder unit construction double overhead camshaft design of 500cc. It was sold under the marque BD, thus perpetuating the Breitfeld-Daněk identity. In 1929 ČKD sold its motorcycle business to Praga Hostivař, which re-branded the motorcycles under the Praga marque. It was one of the main suppliers to the Czechoslovak state of military vehicles during the 1930s.

During the German occupation of Czechoslovakia in World War II, the company was renamed BMM (Böhmisch-Mährische Maschinenfabrik AG) and manufactured arms for the Wehrmacht. The company's most notable products in this era were a light tank of the company's own design – the Panzer 38(t) – and the Jagdpanzer 38(t) tank destroyer, which was built on the Panzer 38(t)'s chassis.

After the war, ČKD was nationalized and became one of the world's leading producers of trams. These were produced by its subsidiary company, ČKD Tatra (commonly known as Tatra, when being referred to in connection with trams, but separate from the company Tatra). From the 1930s to the 1950s, ČKD also supplied electrical equipment for several trolleybuses built by Tatra, as well as ones built by Škoda until Škoda began manufacturing its own such equipment. ČKD Tatra also manufactured metro cars and diesel locomotives, that were exported into other communist countries. One such example from the T-series of Czech locomotives was exported into the USSR and given a Russian designation "ЧМЭ" (ChME3) there. In the socialist era ČKD employed up to 50,000 people.
