Mirza Muhammad Nikusiyar or Nekusiyar or Neku Siyar, also known as Timur II, was a claimant to the Mughal throne.

[2] Neku Siyar was born in 1679, the son of Mughal prince Muhammad Akbar,[3] and a grandson of emperor Aurangzeb.

[7] On May 1719, Birbal, the local governor of the Agra Fort, used Neku Siyar as a puppet and proclaimed him as the emperor.

Neku Siyar was brought out of old harem prison on 18 May 1719 and proclaimed the Mughal emperor, challenging the legitimacy of the reign of his nephew Rafi ud-Darajat.

The Sayyid brothers acted quickly to secure the position of their puppet emperor, retaking the Agra Fort by June and deposing Birbal and Neku Siyar from their posts.
