Dasymutilla sackenii, also known as Sacken's velvet ant, is a species of velvet ant, actually a type of wasp.

[2][3]: 399  As with most velvet ants, the males have wings and the females are wingless.

The females of this species have cream-colored fuzz (setae) on their backs and black fuzz on their ventral side and legs.

[1] D. sackenii superficially resembles Dasymutilla albiceris and they also have a similar geographic distribution.

[3]: 350 The specific name honors 19th-century German diplomat and entomologist Carl Robert Osten-Sacken.
