The invention relates to an autogyro rotor blade for generating lift by autorotation, comprising a root-side inner profile region (9), which has a first profile (21c), a tip-side main profile region (10), which has a second profile (21e) different from the first profile (21c), and a profile depth curve (22) that decreases monotonically in the longitudinal direction of the autogyro rotor blade (1) from the region of the blade root (2) toward the blade tip (3). According to the invention, the autogyro rotor blade (1) has torsion having a torsion curve (23) that decreases monotonically from the region of the blade root (2) toward the blade tip (3), wherein the torsion curve (23) has a variable slope in the inner profile region (9) and/or main profile region (10), such that the torsion curve (23) is concavely curved in said region (9, 10).
