A gate locking assembly includes an anchor shaft that has rectilinear-shaped first and second sections orthogonally registered with each other. The first section travels horizontally along a linear plane and the second section is disposed vertically and travels adjacent to a vertical frame portion of an existing gate. A rectilinear tubular rod has an axial bore formed therein and a proximal end positioned about the first section of the anchor shaft. The rod has a distal end provided with a pair of apertures formed in an outer surface thereof, and lays contiguously against the gate. A bracket is coupled to the vertical frame portion of the gate and has a sleeve oriented along a longitudinal length of the vertical frame portion. A lock is attached to the rod and channeled through the passageway.
