Bartlett Laffey (1841 – March 22, 1901) was an Irish-born United States Navy sailor and Medal of Honor recipient.

Born in County Galway, Ireland, he enlisted in the United States Navy from Massachusetts on March 17, 1862, and was assigned to stern wheel gunboat USS Marmora.

On March 5, 1864, the Confederates launched a heavy attack on Union positions at Yazoo City, Mississippi.

His granddaughter, Miss Eleanor Fogerty, christened the first USS Laffey (DD-459), a Benson class destroyer, in 1941.

The second USS Laffey is now preserved as a museum ship and is registered as a National Historic Landmark.
