A system for controlling pile orientation comprises a pile ( 14 ) and a pile guide ( 20 ) for supporting the pile as it is driven into a substrate, the pile guide comprising a base frame ( 10 ) and a pile guide member ( 22 ) mounted on the base frame. The pile ( 14 ) and the pile guide member ( 22 ) have slidaby interengaging profiles ( 30, 40 ) comprising first and second parts ( 32, 42 ), which are configured to axially rotate the pile to correct any misorientation relative to the pile guide as the parts slide past each other, and third and fourth parts ( 34, 44 ), which are configured to maintain a predetermined orientation of the pile relative to the pile guide once any misorientation has been corrected by interengagement of the first and second parts.
