We construct a manifestly N=(4,0) world-sheet supersymmetric twistor-like formulation of the D=6 Green-Schwarz superstring, using the principle of double (target-space and world-sheet) Grassmann analyticity. The superstring action contains two Lagrange multiplier terms and a Wess-Zumino term. They are written down in the analytic subspace of the world-sheet harmonic N=(4,0) superspace, the target manifold being too an analytic subspace of the harmonic D=6 N=1 superspace. The kappa symmetry of the D=6 superstring is identified with a Kac-Moody extension of the world-sheet N=(4,0) superconformal symmetry. It can be enlarged to include the whole world-sheet reparametrization group if one introduces the appropriate gauge Beltrami superfield into the action. To illustrate the basic features of the new D=6 superstring construction, we first give some details about the simpler (already known) twistor-like formulations of D=3, N=(1,0) and D=4, N=(2,0) superstrings.
