PU-Sarruma (PU-LUGAL-ma, <sup>m</sup>PU-à  Ã r-(rù)-ma, possibly representing Hià ¡mi-à  arruma) is a conjectured pre-Empire king of the Hittites. The conjecture was forwarded by Emil Forrer and is not commonly accepted.
He would have reigned around 1600 BC (short chronology).
Hià ¡mi-à  arruma would correspond to the grandfather of Hattusili I and the father-in-law of Labarna I and true father of Papahdilmah, mentioned (but not by name) by Hattusili. Hià ¡mi-à  arruma was also a father of Tawannanna.
Virtually nothing is known of PU-à  arruma's life, who is a very shadowy figure. PU-à  arruma's sons had turned against their father, so that, while he was in the city of à  anahwitta, he named his son-in-law Labarna as his successor. However, Papahdilmah still had support among the king's servants and chief officers.
