James Lewis (1832 – July 11, 1914) was an African-American soldier and Republican politician in Louisiana. Born into slavery and of mixed race, during the American Civil War he left a position as steward on a Confederate steamboat to move to New Orleans, which had been taken over by Union troops. There he helped organize the First Louisiana Volunteer Native Guards, becoming captain of Company K and serving until 1864. After the war he became politically active in the Republican Party during the Reconstruction era, where he was an ally of several other leading men of color in the city and state.
