A variable camber turbomachine vane is described in which at least one of a front part and a rear part is pivotable relative to the other about a pivot axis to vary the camber of the vane, and the facing end surfaces of the front and rear parts form a junction which provides for the continuity of the intrados and extrados faces of the vane as well as for sealing between these two faces. The pivot axis is offset on the intrados face side relative to the mean surface of the vane by a distance which is preferably at least one third of the thickness of the vane. Also, a cover is provided on the intrados side of the vane for masking the recess which is created in the intrados face at the junction when the camber of the vane is varied.
