William Frank Browne (died September 12, 1867) was an American military photographer noted for his prolific work during the Civil War.

Soon afterward, he began working as the camp photographer of the 5th Michigan Cavalry, staying with them in their winter encampment at Stevensburg, Virginia.

He took some of the earliest portrait photographs of George Armstrong Custer, commander of the Michigan Brigade, after that officer's promotion to Brigadier General.

A collection of 120 photographs taken by Browne were published by Gardner under the title, View of Confederate Water Batteries on James River.

After the war, Browne returned to his native Northfield, where he died of consumption in 1867.
