Cona, also Cuona Lake or Tsonag Lake ({{zh|t=錯那湖 |s=错那湖 |p=Cuònà Hú}}), is a major lake of northern Tibet Autonomous Region, China. It is located in Amdo County, Nagqu, west of the road between Nagqu Town and Pana Town. The lake is considered holy to the Tibetans especially in the Bon religion, as it is seen as the "soul lake" of the Razheng Living Buddha.{{cite book|last1=An|first1=Caidan|author2=刘浚|author3=李金慧|author4=谢涛|title=Travel Guide to Tibet of China|url=https://books.google.com/books?id=n_WNBLU660AC&pg=PA18|accessdate=9 April 2012|year=2003| publisher = China Intercontinental Press|isbn=978-7-5085-0374-5|page=18}} The smaller Ganong Lake lies almost adjacent to the southeast.
