The living tree is located in Huanggou Forest, in northeast China's Jilin Province.
It is more than 40 metres tall and has a diameter of 1.68 metres, said Yang Yongsheng, head of the forest administration.
According to the provincial forestry department, it is the oldest - believed to be about 3,000 years old - and the best-preserved Chinese yew in Jilin.
It is among more than 30 Chinese yew trees discovered recently, state-run Xinhua news agency reported.
Since many of the trees have been harvested to extract taxol, used to treat cancer, the species is now under first-grade national protection for endangered plants.
