Erythrina crista-galli is a flowering tree in the family Fabaceae, native to Argentina, Uruguay, southern Brazil and Paraguay. It is widely planted as a street or garden tree in other countries, most notably in California (in the United States).

In English it is often known as the Cockspur Coral Tree.
