Phlox caespitosa is a species of phlox known by the common name tufted phlox. It is native to western North America from British Columbia through the Great Basin to New Mexico, where it grows in scrub, woodland, and other open plateau habitat.

In the past, this species and Phlox douglasii have been erroneously lumped together.
