Saw E Kan-Kaung (Burmese: စောအဲကံကောင်း, [sɔ́ ʔɛ́ ɡàɰ̃ ɡáʊɰ̃]; 1313/14–1330) was king of Martaban for 49 days in 1330. E was the last Martaban king to pledge allegiance to Sukhothai. The eldest son of King Saw O (r. 1311–1323) was placed on the throne by Queen Sanda Min Hla, who made herself his chief queen. Although he had fought against Martaban's former overlord Sukhothai, after his accession, E quickly mended fences with his maternal grandfather King Loe Thai of Sukhothai. But Queen Sanda Min Hla was dissatisfied with the young king, and poisoned him seven weeks later. His assassination provoked an invasion by Sukhothai, which Sanda Min Hla and her new king Binnya E Law (r. 1330–1348) decisively defeated.
