3830 (pronounced Thirty-eight thirty) is a 4-6-2 steam locomotive operated by the New South Wales Government Railways between 1949 and 1967. It has been preserved by the Powerhouse Museum and is based at the Trainworks Railway Museum, Thirlmere. It was operational from 1997 until 2009 and was scheduled to return to service in 2016 before the need for more extensive boiler repairs was discovered.

3830 was built in 1949 by the New South Wales Government Railways', Eveleigh Railway Workshops as the last of thirty 38 class locomotives built to haul express trains. 3830 was the last steam locomotive built in New South Wales. The first five were built by Clyde Engineering to a streamlined design, whilst the later 25 locomotives in the class were built by Eveleigh and Cardiff Locomotive Workshops and were unstreamlined.

Construction was delayed mostly due to material shortages during World War II. 3830 was the last engine completed and entered service on 27 September 1949. It was allocated to Eveleigh Locomotive Depot until January 1960, before moving to Lithgow. It returned to Eveleigh in September 1960, operating from Broadmeadow between January and April 1961, before receiving its last overhaul during which it was repainted green.

In April 1962, it along with 3813 hauled the inaugural standard gauge Spirit of Progress from Albury to Sydney. In September 1966, it was reallocated to Enfield Locomotive Depot. On 22 October 1967 it made a farewell run from Sydney to Wyong on a New South Wales Rail Transport Museum special. It made its final journey on 31 October 1967 on a freight train from Moss Vale to Enfield. Over 18 years it travelled 1.7 million kilometres.
