The invention provides a variable wingspan wing and an unmanned aerial vehicle with the variable wingspan wing, the variable wingspan wing comprises an inner wing assembly, an outer wing assembly, a driving assembly and a heating unit, the inner wing assembly comprises an inner wing skin, a first inner spar and a second inner spar, and the outer wing assembly comprises an outer wing skin, a first outer spar and a second outer spar. The outer wing skin comprises a first outer-layer skin, a shape memory alloy sheet and a second outer-layer skin, the shape memory alloy sheet is made of shape memory alloy, the first outer spar is movably arranged in the first inner spar groove, the second outer spar is movably arranged in the second inner spar groove, and the shape memory alloy sheet is made of shape memory alloy. The driving assembly is used for driving the first outer spar to move along the first inner spar groove and driving the second outer spar to move along the second inner spar groove, and the heating unit is used for heating the shape memory alloy sheet in the unfolding state of the variable-wingspan wing. According to the technical scheme, the technical problem that in the prior art, the aerodynamic shape of the wing surface is discontinuous in the deformation process of a variable wingspan aircraft is solved.
