Some demonstrative embodiments include apparatuses, systems and/or methods of wireless communication beamforming. For example, an apparatus may include a wireless communication unit to process a beamforming frame communicated between a beamforming initiator station and a beamforming responder station subsequent to a Transmit (Tx) sector sweep by the beamforming initiator station, wherein transmission of the beamforming frame is from a first station of the beamforming initiator station or the beamforming responder station to a second station of the beamforming initiator station or the beamforming responder station, the beamforming frame comprises an indication of a selected Tx sector, based on the Tx sector sweep, to be used by the first station for transmitting a directional beamformed transmission to the second station.
