Jagadhri is a city and a municipal council in the Yamunanagar district of the Indian state of Haryana. This town lies adjacent to the city of Yamunanagar. The demarcation line between the two is difficult to discern. Jagadhri is around 90  km away from Chandigarh, the capital city of Haryana state. This town is known for the cluster of brass and copper industries. Jagadhri is known as the "Brass City" of India. 

Jagadhri, corrupted form of its old name Yugandhari, was named after the king of the Yugandharas. Yugandharas find mention in Mahabharata as well as Buddhist texts as region with warriors or mountains. Yugandhara likely was used for a region inhabited by a tribe of that name and it comprised some mountainous tracts also which were given the same name.

Excavations have found the punch marked square coins, a Greek hemidrachm coin of Indo-Greek king Apollodotus I or Apollodotus II (1st and 2nd century BCE ) and one of Antimachus I/Antimachus II (2nd century BCE), a gold coin of Samudragupta (ruled 336-380 CE) and other coins of the period up to the Prithviraj Chauhan and Tomara dynasty kings of Delhi. It was likely the capital city of a Janapada. There are few places which have signs of Ashoka like Topra kalan, Chaneti, Sugh and Lohgarh. Topra kalan is the place where the Ashoka pillar having Pali inscriptions was originally installed by Ashoka. This pillar was uprooted by Mughal invader Ferozeshah Tughlaq and was moved to Delhi and reinstalled. Chaneti has one full size Buddhist stupa excavated similar to those found in Sanchi and Sarnath. Sugh also had signs of Buddhism which have been razed by local natives.
