Vachellia schaffneri, the twisted acacia or Schaffner's acacia, is a tree native to Mexico and the southwestern United States (Texas).

It has alternate, bipinnately compound leaves that are generally similar to those of other Vachellia species.

The seedpods are long, fuzzy, ripen in late summer, and are consumed by livestock.

Vachellia schaffneri trees serve as food for animals.

Goats and sheep browse leaves from the tree and eat the fuzzy beans when available late in the summer.
