Canavalia hawaiiensis commonly known as ‘āwikiwiki or Hawaiian jackbean, is a low growing vine of the pea family (Fabaceae) and endemic to Hawai'i.

The leaflets making up the leaves are ovate to elliptic in shape and may be quite wide relative to their length.

The top of the leaves are moderately to densely covered in fine hairs that lay down against the surface of the leaflets.

In 1966 Francis Raymond Fosberg published a description of it as a variety of the Hawaiian species Canavalia galeata, but this classification is not generally accepted.

In the 1970s Harold St. John described four new species that are now considered to be synonyms of C. hawaiiensis including Canavalia kauaiensis.
