The Manapa-Tarhunta letter (CTH 191; KUB 19.5 + KBo 19.79) is a Hittite letter discovered in the 1980s. It was written by a client king called Manapa-Tarhunta to an unnamed Hittite king around 1295 BCE. The only datable Manapa-Tarhunta was the one who became undisputed king of Seha River around the time of the death of Arnuwanda II (1322 BCE). This letter further mentions a Kupanta-Kurunta. A treaty between Mursili II (1322-1295 BCE) and a Kupanta-Kurunta, who is king of Mira (Western Asia Minor), survives which mentions this Manapa-Tarhunta as still alive.
