James M. Johnson (December 8, 1832 – February 15, 1913) was an American soldier and Arkansas politician. During the American Civil War he was a southern unionist and officer in the Union Army; serving as an aide to multiple generals and later commanded the 1st Arkansas Infantry Regiment (Union), eventually being made a brevet brigadier general. Following the war he would become the 2nd Lieutenant-Governor of Arkansas and later the 10th Secretary of State of Arkansas. During his tenure in Arkansas politics Johnson formed his own faction in the Arkansas Republican Party, which went against the policies of Governor Powell Clayton. The two men later tried to impeach the other on trumped up charges. Though Johnson was never convicted he lost his political support and left politics.
