A pile guide, for supporting a pile as it is driven into a substrate, has a base frame and a pile guide member mounted on the base frame. The base frame comprises one or more substrate-engaging supports, moveable between an inoperative position and an operative position, with movement of the or each substrate-engaging support into the operative position resulting in an increase in the area of the base frame which, in use, rests on the substrate.
