Gassulawiya was a Hittite queen of the king Mursili II, ruler of the Hittite Empire (New kingdom) ca. 1321–1295 BC ( short chronology). 
Gassulawiya is known to have had several children including a daughter named Massanauzzi (referred to as Matanaza in correspondence with
Ramesses II) married to Masturi, a ruler of a vassal state and three sons named Muwatalli, Hattusili III and Halpasulupi. Mursili had further children with a second wife named Tanuhepa. Their names have not been recorded however.
