Queen Arjayadengjayaketana of Bali was a ruler of that island in 1200.
Very little is known about her.
She was a member of Jaya Dynasty (Warmadewa dynasty) and successor of King Jayapangus, who was maybe her father.
Arjayadengjayaketana was likely a mother of King Haji Ekajayalancana. She was a regent for him.
She and her son were succeeded by King Bhatara Guru Śri Adikuntiketana.
