Abstract: A chainsaw holder adapted for receiving a chainsaw bar and chain within an interior compartment of a mounting piece. A pressure piece fits at least partly within the interior compartment and is forced by an operator against the chainsaw bar to capture it within the compartment. The operator is adjustable to release the chainsaw bar. The operator may be a screw operator which bears upon the pressure plate. The pressure plate may have an end flange for keeping it positioned within the interior compartment. The mounting piece preferably has flanges which allow fasteners to extend therethrough and secure the apparatus to the side wall of a supporting structure such as the wall of a pickup bed.
