The 11th Panchen Lama controversy centers on the 28 year-long enforced disappearance of Gedhun Choekyi Nyima and on the recognition of the 11th Kunsik Panchen Lama. The Panchen Lama is considered the second most important spiritual leader in Tibetan Buddhism after the Dalai Lama. Following the death of the 10th Panchen Lama, the 14th Dalai Lama recognized Gedhun Choekyi Nyima in 1995. Three days later, the People's Republic of China (PRC) abducted the Panchen Lama and his family. Months later, the PRC chose Gyaincain Norbu as its proxy Panchen Lama. During the traditional search process led by Chadrel Rinpoche, he indicated to the Dalai Lama that all signs pointed to Gedhun Choekyi Nyima, while the Dalai Lamas and Panchen Lamas recognize each other's incarnations. The PRC had established its own search committee, which included Chatral Rinpoche and other monks, and wanted to use a lottery system referred to as the Golden Urn. Neither Gedhun Choekyi Nyima nor his family have been seen since the abduction. Chatral Rinpoche was also arrested by Chinese authorities the day of the abduction.

The Panchen Lama is a tulku of the Gelug school of Tibetan Buddhism. The Panchen Lama is one of the most important figures in the Gelug tradition, with its spiritual authority second only to the Dalai Lama. Along with the council of high lamas, he is in charge of seeking out the next Dalai Lama. Panchen is a portmanteau of Pandita and Chenpo, meaning "great scholar".
