Colonel Archibald Stephenson Dobbins (c. 1827 – c. 1878) was an officer of the Confederate army who commanded a cavalry regiment in the Trans-Mississippi Theater of the American Civil War.

[1] When Confederate Major-General Thomas C. Hindman was appointed commanding officer of the District of Arkansas in the summer of 1862, he brought Dobbins with him from Mississippi to Little Rock as a volunteer aide-de-camp on his personal staff.

[1] Dobbins' cavalry regiment was assigned to a division commanded by Brigadier-General Lucius M. Walker and fought in several battles, skirmishes, and raids throughout the Trans-Mississippi Department.

[2] Dobbins received a field promotion to brigadier-general, but was never nominated by President Davis nor confirmed by the Confederate Senate in part due to the isolated condition of the Trans-Mississippi Theater toward the end of the Civil War.

[4] An article in the August 7, 1881, edition of The Standard, an English language newspaper out of Buenos Aires, states that eight Scottish colonists from Greenock had contracted with Dobbins five years earlier for their passage to Port Desire, Argentina.

[5] Theories about Dobbins' fate range from murder at the hands of Indians, a natural death in the Patagonia region of Argentina, to a desire to abandon his family.
