The Albatros C.XIII was a German two-seat, single-engine, biplane light fighter aircraft built in 1917.

The C.XIII was built along the lines of the single seat Albatros D.Va but was a two-seater, larger by about 10% in span and by 6% in length.

It was intended to fall into the newer Idflieg two seat CL-class, reserved for lighter two-seat fighters.

[1] The round cross section, plywood-covered fuselage was, apart from the second, tandem open cockpit similar in appearance to that of the D.Va, smoothly tapering to the nose with lines that merged into those of the spinner.

As with the single-seater, the inline Mercedes D.III engine was largely enclosed but had its six upper cylinders exposed.
