We propose a new superspace formulation for N=(4,4) conformal supergravity intwo dimensions. This is based on a geometry where the structure group of thecurved superspace is chosen to be SO(1,1) x SU(2)_L x SU(2)_R. The off-shellsupergravity multiplet possesses super-Weyl transformations generated by anunconstrained real scalar superfield. The new supergravity formulation turnsout to be an extension of the minimal multiplet introduced in 1988 by Gates et.al. and it allows the existence of various off-shell matter supermultiplets.Covariant twisted-II and twisted-I multiplets respectively describe the fieldstrength of an Abelian vector multiplet and its prepotential. Moreover, weintroduce covariant bi-projective superfields. These define a large class ofmatter multiplets coupled to 2D N=(4,4) conformal supergravity. They are theanalogue of the covariant projective superfields recently introduced for 4D and5D matter-coupled supergravity but they differ by the fact that bi-projectivesuperfields are defined with the use of two CP^1 instead of one. We conclude bygiving a manifestly locally supersymmetric and super-Weyl invariant actionprinciple in bi-projective superspace.
