The invention discloses a foldable propeller arm assembly. The foldable propeller arm assembly comprises a base and propeller arms, wherein the propeller arms are pivoted on the base and have an unfolded state and a folded state; a first clamping and connecting part near the base is arranged on each propeller arm. The foldable propeller arm assembly also comprises first locking elements which are rotationally connected with the base; a second clamping and connecting part is arranged on each of the first locking elements; and the first locking elements are used for rotating to engage the second clamping and connecting parts with the first clamping and connecting parts when the propeller arms are in the unfolded state and are in an abutted position limiting state with the base, so that the propeller arms maintain the unfolded state. The invention also discloses an unmanned aerial vehicle. The propeller arms adopt an integral pivoting structure, so that the integral strength and rigidity of the propeller arms are effectively ensured; the integral structure stability of the unmanned aerial vehicle is enhanced; and meanwhile, the propeller arms can be folded and unfolded, so that the occupied space of the unmanned aerial vehicle when the unmanned aerial vehicle is not used is greatly reduced. The technical scheme provided by the invention has the characteristics that the structure is simple, the operation is simple and convenient, and the like. The operation convenience of the propeller arms is greatly improved.
