The Victorian Railways G class is a class of steam locomotives built for the Victorian Railways 2 ft 6 in gauge branch lines by Beyer, Peacock & Company. They were introduced in 1926 to increase train sizes and reduce losses on these lines. Their tractive effort was comparable to the most powerful branch line locomotives on the Victorian Railways 5 ft 3 in (1,600 mm), the K class.
