A mast raising assembly includes a base that is securable to a horizontal support surface. A tube is insertable into the base such that the tube is vertically oriented. A winch is coupled to the tube and a pair of lower pulleys is each rotatably coupled to the tube. A mast is pivotally coupled to the tube. The mast is positionable in a raised position and a folded position. A plurality of upper pulleys is each of the upper pulleys is rotatably coupled to the mast. A cable extends between the winch, the lower pulleys and the upper pulleys. The cable urges the mast into the raised position when the winch is rotated in a raising direction. Additionally, the cable urges the mast into the folded position when the winch is rotated in a lowering direction.
