A variable stator vane (15) airfoil (31) is mounted on a button (54) centered about a rotational axis (20) and includes circular leading and trailing edges (52, 53) circumscribed about the rotational axis (20) at a button radius (R) Contoured pressure and suction sides (58, 59) extend from the circular leading edge (52) to the circular trailing edge (53) and are recessed inwardly from a perimeter (22) circumscribed about the rotational axis (20) at the button radius (R) . One of upstream and downstream pressure side portions (24, 26) of the contoured pressure side (58) is straight and another of the upstream and downstream pressure side portions (24, 26) is curved. One of the upstream and downstream suction side portions (28, 30) is straight and another of the upstream and downstream suction side portions (28, 30) is curved. One of the upstream pressure side portion (24) and upstream suction side portion (28) is straight and another of the upstream pressure side portion (24) and upstream suction side portion (28) is curved.
