Tsewang Rabtan or Tsewang Rapten (died 1727) was a Choros-Oirat prince and the Khun Tayishi of the Zunghar Khanate from 1697 (following the death of his uncle and rival Galdan) until his death in 1727. He was married to Lha-bzang Khan's sister.
Tsewang Rabtan married his daughter to Lha-bzang Khan's son in 1714. He used the occasion to treacherously destroy some of Lha-bzang's troops in preparation for an invasion of Tibet. He consolidated Zunghar power by 1715, and in 1717 sent one army of 300 to Amdo to retrieve the 7th Dalai Lama, planning to consolidate Tibetan support by bringing him to Lhasa, and another army of 6000, led by his brother Tsering Dondup, that successfully took Lhasa from the Khoshut and killed Lha-bzang Khan.
