The Mongolian Democratic Union (MDU) (Mongolian: Монголын Ардчилсан Холбоо, romanizedMongolyn Ardchilsan Kholboo) is a Mongolian political movement, nonprofit, and non-governmental organization founded in 1989. It was the first democratic movement to challenge the dominance of the Mongolian People's Revolutionary Party, which ruled the Mongolian People's Republic as the sole legal party from 1921 until 1990.

In February 1990, the MDU established the Mongolian Democratic Party, the first and foremost opposition party from 1990 to 1992, which later on merged into the modern Democratic Party.
