3820 (pronounced Thirty-eight twenty) is a 4-6-2 steam locomotive operated by the New South Wales Government Railways between 1947 and 1970. It has been preserved by the Trainworks Railway Museum, Thirlmere.

3820 was built in 1947 by the New South Wales Government Railways', Eveleigh Railway Workshops as the 20th of 30 38 class locomotives built to haul express trains. The first five were built by Clyde Engineering to a streamlined design, whilst the later 25 locomotives in the class were built by the NSWGR's Eveleigh and Cardiff Locomotive Workshops and were unstreamlined.

Construction was delayed mostly due to material shortages during World War II. It was at various times allocated to Eveleigh, Enfield, Lithgow and Broadmeadow Locomotive Depots.

During the rundown of steam operation in New South Wales, 3820 had the distinction of some lasts:

Upon withdrawal, 3820 was placed in the custody of the New South Wales Rail Transport Museum and based at Enfield Locomotive Depot operating excursion trains including a journey to Melbourne with 3801, and the Last Run which it triple headed with 3203 and 3526 to Tarana on 21 April 1973 before the Public Transport Commission banned main line steam operation.
