Ehretia anacua is medium-sized tree found in eastern Mexico and southern Texas in the United States. It is a member of the [family Ehretiaceae. One of its common names, anacua, is derived from the Mexican Spanish word anacahuite, as is that of the related Cordia boissieri, the anacahuita.

It is also known as knockaway, a corruption of anacua, and sandpaper tree. Alternate spellings are anaqua and anachua.
