William W. Wells, Jr. (December 14, 1837 – April 29, 1892) was a businessman, politician, and general in the Union Army during the American Civil War who received a Medal of Honor for gallantry at the Battle of Gettysburg.

A few days later, in the savage cavalry melee at the Battle of Boonsboro in Maryland, Wells was wounded by a sabre cut.

At Culpeper Court House, Virginia, September 13, 1863, he charged the enemy's artillery with his regiment and captured a gun, and was again wounded, by a shell.

In the Battle of Tom's Brook, Virginia (October 9, 1864), a cavalry action, Wells commanded a brigade of Custer's division, and at Cedar Creek, his brigade took a foremost part in turning the rout of the morning into a decisive victory at nightfall, capturing forty-five of the forty-eight pieces of artillery taken from Jubal Early's fleeing army.

At Appomattox Court House, on the morning of the surrender of the Army of Northern Virginia, Wells' brigade had started on its last charge and was stopped by General Custer in person.

Following Appomattox, the departure of Sheridan and Custer for Texas left Wells as the ranking officer and last commander of the Cavalry Corps of the Army of the Potomac.

He was succeeded by James Stevens Peck and accepted appointment as collector of customs for the district of Vermont, a position which he filled with efficiency and credit for thirteen years.

At the end of that time, he resumed his active connection with the business house known the world over as the Wells Richardson Company, manufacturer of Paine's Celery Compound.

He was a member and a vestryman of St. Paul's church, and was one of the trustees of the Young Men's Christian Association of Burlington, and one of its most liberal supporters.

His sudden death from angina pectoris in New York City removed, while in the prime of life, a most genial, courteous and kind-hearted man, a gallant soldier, and one of the most respected citizens of the Green Mountain state.
