Ujjayanta Palace is a former royal palace situated in Agartala, the capital of the Indian state of Tripura, and currently serves as the meeting place of the Tripura Legislative Assembly. Ujjayanta Palace is a tourist attraction of Agartala, and tours are conducted by the Tripura Tourism Department. The name Ujjayanta Palace was given by Rabindranath Tagore.

Ujjayanta Palace compound covers an area of approximately one km². The main block covers 800 acres (3.2 km2), comprising public halls such as the Throne room, the Durbar hall, Library and the Reception hall. The Neoclassical palace was designed by Sir Alexander Martin of Messrs Martin & Co. The Chinese Room is particularly notable, the ceiling of which was crafted by artisans brought from China. The two-storied palace has three large domes, the largest of which is 86 ft (26 m) high from the ground, and which rests atop a four-storied central tower. The palace has tiled floors and carved front doors. Newer attractions are the musical fountain installed in front of the main entrance, and the night-time floodlights. The grounds are laid out as formal Mughal gardens adorned with fountains. There are two large artificial ponds on either side of the garden.

Several Hindu temples occupy plots adjacent to Ujjayanta Palace, dedicated to Lakshmi-Narayan, Uma-Maheshwari, Kali and Jagannath.
