A pile guide (10) for supporting a pile as it is driven into a substrate, comprising: a base frame (12) having a planar substrate-engaging surface (14) and a pile guide member (16) configured to guide a pile in a predetermined direction therethrough as it is driven into a substrate (18), the pile guide member (16) being mounted on the base frame (12) via a plurality of support members (20) extending therebetween; characterised in that at least one of the plurality of support members (20) has an adjustable length, with length adjustment of the or each support member (20) enabling the predetermined direction to be varied relative to the planar substrate-engaging surface (14) of the base frame (12).
