The C30 class (formerly S.636 class) is a class of steam locomotives built by Beyer, Peacock & Company and Eveleigh Railway Workshops for the New South Wales Government Railways (NSWGR) of Australia.

These 4-6-4 tank locomotives were specifically designed to haul Sydney's ever increasing suburban traffic, particularly over the heavy grades on the Northern, North Shore and Illawarra lines.
