Ratcheting shape memory alloy actuators and systems and methods including the same are disclosed herein. The ratcheting shape memory alloy actuators include a ratcheting assembly that is operatively coupled to a first bracket and a shape memory alloy element that is operatively coupled to the ratcheting assembly and to a second bracket. The first bracket is configured to be operatively coupled to a first structure, while the second bracket is configured to be operatively coupled to a second structure. The shape memory alloy element is configured to apply a motive force to the ratcheting assembly upon deformation between a first conformation and a second conformation. The ratcheting assembly is configured to utilize the motive force to selectively adjust an orientation of the first structure relative to the second structure.
