葡萄桉（学名：Eucalyptus botryoides）为桃金娘科桉属下的一个种。

Eucalyptus botryoides, commonly known as the Bangalay or Southern Mahogany, is a small to tall tree native to southeastern Australia. Reaching up to 40 metres (130 feet) high, it has rough bark on its trunk and branches. It is found on sandstone- or shale-based soils in open woodland, or on more sandy soils behind sand dunes. The white flowers appear in summer and autumn. It reproduces by resprouting from its woody lignotuber or epicormic buds after bushfire. E. botryoides hybridises with the Sydney blue gum (E. saligna) in the Sydney region. The hard, durable wood has been used for panelling and flooring.
