Eucryphia cordifolia, the ulmo, is a species of tree in the family Cunoniaceae.

The natural habitat is along the Andes Range from 38 to 43°S, and up to 700 meters (2300 ft) above sea level.

It is an exquisite tree with a thick trunk and broad crown and can become over 12 m (39 ft) high.

Its flowers contain a highly appreciated aromatic nectar, harvested by introduced European bees and commercialized as ulmo honey (miel de Ulmo).

It grows well on the western coast of Scotland, UK, where several notable specimens exist, including possibly the most northerly cultivated example at Inverewe Garden.
