Dharmanagar is located in the northeastern region of Tripura, sharing its northern borders with the neighboring state of Assam. The city is situated along the banks of the Juri River, a perennial river that heavily influences the local geography and agriculture. The landscape is a picturesque blend of fertile river valleys, undulating plains, and low-lying hillocks locally known as *tillas*.
The region's natural resources are primarily agricultural and forest-based. The surrounding areas are characterized by dense tropical foliage, bamboo groves, and expansive tea gardens. The soil in the river basin is highly fertile alluvial soil, while the hilly areas feature laterite soil suitable for plantation crops like rubber and tea.
