The LVG C.II was a 1910s German two-seat reconnaissance biplane designed at the Luft-Verkehrs-Gesellschaft for the Luftstreitkräfte.
The C.II was developed from the LVG B.I, with the pilot and observer positions reversed, adding a ring-mounted machine gun to the rear.
The increase in weight required a larger engine, the Benz Bz.III.
