USS Chehalis (PGM-94/PG-94) was an Asheville-class gunboat of the U.S. Navy and the second ship to be named Chehalis. Chehalis was launched 8 June 1968 at the Tacoma Boatbuilding Company. She was commissioned 8 November 1969. The vessel was named in honor of Chehalis, Lewis County, Washington State. Later, she was transferred to Naval Sea Systems Command and renamed Research Vessel Athena.

The Chehalis was powered by a combination of two Cummins diesel engines and a General Electric LM-1500 gas turbine. Pneumatic actuators allowed the power source to be switched between the two sources.
