A single hand folding structure for an umbrella folding stroller includes a connecting element is utilized to connect between a single hand release structure and a driving piece of a folding set. The single hand release structure is disposed on a handle bar of a frame of the umbrella folding stroller so as to allow a user to directly operate with a single hand to release the folding set. An elastic element of the frame is utilized to assist the partial folding of the frame such that the user can directly push the handle bar to fold the frame. Thus, the user avoids using a foot to release the frame to fold and, subsequently, prevents damage to shoes.
