The Duewag Y is a series of diesel multiple units (DMUs) manufactured between 1965 and 1988 for Danish rail operators by the West German company Waggonfabrik Uerdingen. A total of 160 cars were built: 76 motor cars, 23 trailer cars, and 61 control cars.

Introduced in 1965 by Danish private operators and later in 1984 by DSB, the Y-type units began being phased out in the 1990s. DSB ceased operations in 2010, and the last run on Danish rails, by a private operator, occurred in 2012. All units were scrapped except one preserved for museum purposes and another exported to Poland in 2008. In 2010, this unit operated in Kuyavian-Pomeranian Voivodeship under Arriva RP, but it was later placed in long-term reserve with no plans for reactivation.
