Ratna Manikya II (c. 1680 – 1712) was the Maharaja of Tripura from 1685 to 1693 and again from 1695 to 1712. Only a small child when he became ruler, Ratna spent much of his life under the control of external forces, having been used as a puppet-monarch by domineering relations as well as being both deposed and enthroned by the powerful Mughal Empire. He was eventually killed in a coup orchestrated by his younger brother.
