Ganden Monastery or Ganden Namgyeling or Monastery of Gahlden is one of the "great three" Gelug university monasteries located in Dagzê County, Lhasa, Tibet. The other two are Sera Monastery and Drepung Monastery. Ganden Monastery was founded in 1409 by Je Tsongkhapa Lozang-dragpa, founder of the Gelug order. The monastery was destroyed after 1959, but has since been partially rebuilt. Another monastery with the same name and tradition was established in Southern India in 1966 by Tibetan exiles.
