Zamyn-Üüd (Mongolian: Замын-Үүд; ᠵᠠᠮ ᠤᠨ ᠡᠭᠦᠳᠡ, road's gate) is a sum (district) of Dornogovi Province in southeastern Mongolia.

The population of Zamyn-Üüd was 11,527 in 2008.^[1]

Zamyn-Üüd's actual name comes from the former Dzamiin Üüde settlement located 101 kilometres (63 mi) northwest from the modern town (44°30′N 111°15′E / 44.500°N 111.250°E).^[2]

The town is located on the old trade route between Beijing and Urga/Ulaanbaatar, and is now the most important border crossing between Mongolia and the People's Republic of China, via Ereen. The border control counted more than 950,000 border crossings in 2004.^[3] In April 2007, the construction of a 432 kilometres (268 mi) paved road from Choir to Zamyn-Üüd via Sainshand began. Completion is planned for October 2007.^[4] However, completion of the road project was pushed back to 2013, with Sainshand to Choir section being finished in September, 2013.^[5] A new expanded road border crossing was also completed in 2013 to relieve delays in crossing from China to Mongolia.^[6]

The "Zamyn-Uud" Free Economic Zone was officially created in 2004. It has an area of 900 ha and is located between Zamyn-Üüd settlement and the Chinese border ^[7]
