Thinkhaya I of Toungoo (Burmese: သင်္ခယာ, in Burmese pronounced as /θɪ̀ɴkʰəjà/) was viceroy of Toungoo (Taungoo) from 1412 to 1415.
Prior to the appointment at Toungoo by King Minkhaung I of Ava, Thinkhaya was governor of Sagu.[3] His title at Sagu was Thiri Zeya Kyawhtin, and he was already governor by 1408.[4] [5] [6] Chronicles do not say when he was appointed to the Sagu post but the previous governor of Sagu, Theinkhathu II, was still alive in 1402.[7] [8]
He died in 1415, and was succeeded by his son Thinkhaya II.[3] He was married to Min Shwe Pan, a granddaughter of King Swa Saw Ke of Ava and great granddaughter of King Kyawswa I of Pinya.[2]
