Joseph Dana Webster (August 25, 1811 – April 12, 1876) was an American civil engineer and soldier most noted for administrative services during the American Civil War, where he served as chief of staff to both Ulysses S. Grant and William T. Sherman.

On the eve of the first day's fighting at Shiloh, Webster was instrumental in massing the artillery in support of Grant's last line of defense near Pittsburg Landing.

On April 4, 1863, President Abraham Lincoln appointed Webster to the grade of brigadier general of U.S. volunteers, to rank from November 29, 1862.

He next served as the Chief of Transportation for the Army of the Tennessee, during the siege of Vicksburg, and later for the entire Military Division of Mississippi.
