Thiri Thu Nandar Mahe, also known as Tharazein Mibaya (also spelt Tharasein Mibaya, Burmese: သရစိမ်းမိဖုရား), was a queen of the fourth rank of King Mindon during the Konbaung dynasty.

[1] Tharazein Mibaya was born to Shwe Kyi, Count of Kyaukpadaung, and his wife Thakhingyi.

When Mindon ascended the throne, she was selected as a fourth-rank queen with her half-sisters and received the appanage of Myotha [my] and Tharazein[note 1] in 1853.

She escaped the massacre at Mandalay Palace of upward of 100 members of the royal family, following an edict by Hsinbyumashin that ordered the killing of almost all possible heirs to the throne.

After the fall of the Konbaung dynasty, the British government deported Tharazein and her daughters to Rangoon on 28 February 1886.
