An adjustable scaffold support for use in supporting construction scaffold plank members includes a vertical guide member defining an elongated vertical guide track. An extension member is slidably received in the guide track and is secured in a selected adjusted position by a spring steel clamp and a set screw. A pivotal support member has a lower end pivotally connected to a lower end of the extension member. A pair of rectangular channel brackets are provided on upper end portions of the extension member and pivotal support member for engagement with a scaffold support plank. The scaffold support includes an A-frame supporting structure provided with selectively extensible ground insertion spikes for securing the scaffold support at an intended location.
