A death erection, angel lust, or terminal erection is a post-mortem erection, technically a priapism, observed in the corpses of human males who have been executed, particularly by hanging.

Priapism may be associated with haematological disorders, especially sickle-cell disease, sickle-cell trait, and other conditions such as leukemia, thalassemia, and Fabry's disease, and neurologic disorders such as spinal cord lesions and spinal cord trauma (priapism has been reported in hanging victims; see death erection).
