The USCGC Bibb (WPG-31) was a 327-foot (100 m) Secretary-Class (also known as "Treasury Class") Coast Guard ship commissioned in 1936. Seven similar "combat cutters" were built and named for secretaries of the United States Treasury. The legendary Bibb was named for U.S. Secretary of the Treasury (July 4, 1844March 7, 1845) George M. Bibb.

The ship saw service in World War II. The ship fought in the Battle of the Atlantic serving as a convoy escort. In February 1943, the convoy came under attack and the S.S. Mallory was torpedoed. Capt. Raney ignored the order to leave the survivors and went back and rescued 202 men from the icy waters. In 1944 Bibb provided convoy escort between the United States and North Africa — mainly to Bizerte in Tunisia. In January 1945 Bibb left Charleston, South Carolina for service in the Pacific theater where, as an AGC, she served temporarily as the home for Commander, Minecraft, Pacific Fleet. Bibb is credited with destroying one Japanese kamikaze aircraft in action at Karema Retto.

In peacetime the Bibb spent time on ocean station providing weather information and beacons to trans-Atlantic traffic. While on ocean station, the Bibb came to the rescue of the airliner, the Bermuda Sky Queen. In the Vietnam War, the Bibb transported John Kerry after he was shot on his Swift boat. It was decommissioned in 1985 and remained docked until it was transported to the Florida Keys for use as an artificial reef. The ship was sunk in November 1987 just outside the coral reef tract, about six miles (10 km) offshore of the island of Key Largo. It lies on its side at a depth of about 130 feet (40 m). Nearby, a second Treasury-Class ship, the USCGC Duane (WPG-33) was also sunk as an artificial reef.
