Albert Gallatin Jenkins (November 10, 1830 – May 21, 1864) was an American politician who served as a senior officer of the Confederate States Army. He served two terms in the United States Congress from 1857 to 1861 and later the First Confederate Congress.

Jenkins was born to the wealthy plantation owner Capt. William Jenkins and his wife Jeanette Grigsby McNutt in Cabell County, in what was then Virginia. After a private education, he attended Marshall Academy when he was fifteen. He graduated from Jefferson College in Canonsburg, Pennsylvania, in 1848 and from Harvard Law School in 1850.

Admitted to the Virginia bar the same year, Jenkins practiced in Charleston. In 1859, he inherited part of his father's sprawling slave plantation. He was named a delegate to the Democratic National Convention in Cincinnati in 1856. That same year, he was elected as a Democrat to the Thirty-fifth and then, in 1858, to the Thirty-sixth United States Congress, serving from 1857 to 1861.

With the outbreak of the Civil War and Virginia's subsequent secession, Jenkins resigned from Congress in early 1861. He raised a company of mounted partisan rangers, which by June was enrolled in the Confederate Army as a part of the 8th Virginia Cavalry, with Jenkins as its colonel. The company was first organized to protect a Virginia flag that had been raised in Guyandotte, which they did until April 20, 1861. He fought at the Battle of Scary Creek on July 17, 1861, taking command of the confederate force when George S. Patton was wounded, and defeating the Union forces. By the year's end, his men had become such a nuisance to the Federals in western Virginia that military governor Francis H. Pierpont appealed to President Abraham Lincoln to send in a strong leader to stamp out the rebellion in the area. Early in 1862, Jenkins was elected as a delegate to the First Confederate Congress. After promotion to brigadier general on August 1, 1862, he returned to active duty. Throughout the fall, his men harassed Union troops and supply lines, including the vital Baltimore and Ohio Railroad.

In September, Jenkins's cavalry raided northern Kentucky and now West Virginia. They briefly entered extreme southern Ohio across from Ravenswood, West Virginia, becoming one of the first organized Confederate units to enter a Northern state. By November 1862, a grand jury in Cabell County returned misdemeanor indictment against Jenkins, however no copy of these indictments remain. These legal issues most likely came about from Jenkins's raiding in the area. In December, Robert E. Lee requested that Jenkins and his men transfer to the Shenandoah Valley.

After spending the winter foraging for supplies, he led his men on a raid in March 1863 through western Virginia, seeking to influence the popular vote which ultimately created the state of West Virginia. During the Gettysburg campaign, Jenkins's brigade formed the cavalry screen for Richard S. Ewell's Second Corps. Jenkins led his men through the Cumberland Valley into Pennsylvania and seized Chambersburg, burning down nearby railroad structures and bridges. During their invasion of Pennsylvania, his brigade, under Jenkins's direction, abducted hundreds of African Americans (most of them free people of color with a few being fugitive slaves), all of whom were forcibly sent southwards and sold into slavery.

He accompanied Ewell's column to Carlisle, briefly skirmishing with Union militia at the Battle of Sporting Hill near Harrisburg. During the subsequent Battle of Gettysburg, Jenkins was wounded on July 2 and missed the rest of the fighting.

Jenkins did not recover sufficiently to rejoin his command until fall 1863, and spent the early part of 1864 in and around Monroe County, West Virginia, assembling cavalry units for John C. Breckinridge's Department of Western Virginia.
