We propose possible new string theories based on local world-sheet symmetries corresponding to extensions of the Virasoro algebra by fractional-spin currents. They have critical central charges {ital c}=6({ital K}+8)/({ital K}+2) and Minkowski space-time dimensions {ital D}=2+16/{ital K} for {ital K}{ge}2 an integer. We present evidence for their existence by constructing modular-invariant partition functions and the massless particle spectra. The dimension 4 and 6 strings have space-time supersymmetry.
