Some demonstrative embodiments include apparatuses, systems, devices and/or methods of packet coalescing. For example, an apparatus may include circuitry and logic configured to cause a first wireless station to process a notification from a second wireless station including transmit (Tx) packet coalescing information, the Tx packet coalescing information including packet type information to define one or more packet types for packet coalescing at the first wireless station, and a coalescing threshold indicator to indicate a coalescing threshold to limit the packet coalescing at the first wireless station; to coalesce a plurality of packets for the second wireless station by buffering the plurality of packets at the first wireless station, the plurality of packets having at least one of the one or more packet types; and, based at least on the coalescing threshold, to process one or more buffered packets of the plurality of packets for transmission to the second wireless station.
