紫玉盘属（学名：Uvaria）是番荔枝科下的一个属，为攀援状灌木植物。该属共有约150种，分布于热带和亚热带地区。

Uvaria is a genus of flowering plants in the soursop family, Annonaceae. The generic name uvaria is derived from the Latin uva meaning grape, likely because the edible fruit of some species in the genus resemble grapes.

Species are distributed throughout the Old World tropics. This large genus had about 150 species, but recent molecular analyses have revealed that several smaller genera belong within Uvaria, increasing its size.
