Birgunj (also Birganj) (Nepali: बिरगंज) is a sub-metropolitan municipality and border town in Parsa District in the Narayani Zone of southern Nepal.
The 6 km long metre gauge railway track from Raxaul was converted to broad gauge by the Indian railways to connect Sirsiya Inland Container Depot (ICD) (also known as Birganj Dry Port) that became fully operational in 2005.
