Jagadhri is a city in Yamuna Nagar district in the Indian state of Haryana. This town is a part of twin towns, constituting Jagadhri and Yamuna Nagar; Jagadhri is the older one and the latter a relatively new town. These twin cities are known as 2 Zones of the Municipal Corporation. There is hardly any demarcation between the two towns and almost impossible, without knowing, where one town ends and where other starts.

The town is famous for its metal works & brassware including utensils; though nowadays the production of brass ware has fallen off, due to high cost. Subsequently, Jagadhari entered into and made its mark in high quality Aluminium and stainless steel products. In addition, Jagadhri has also witnessed the blossoming of a new business, timber trading, in the last decade. There are many shops doing this business these days. There are many old temples, such as LathMar Mandir, Khera Mandir, Gauri Shankar Mandir and Guga Madi Mandir, Devi Mandir (Mansa Devi).
