The NSB class 30 was a 4-6-0 tender steam locomotive formerly used in Norway by Norges Statsbaner. The class 30 engines were an upsized version of the NSB Class 45 engines. Class 30 locomotives were originally intended for use on Dovrebanen, but they were employed throughout the Norwegian rail network. The first of these engines were produced in 1914, the last in 1939.

A total of 45 type 30 engines were completed by Thune which produced 22 engines, and NMI which produced 23 engines. The type 30 was produced in three versions. Class 30a had four cylinder high pressure engine, while class 30b and 30c were compound engines. 18 units were made of the lightest version the 30a (numbered 256-258, 271-282, and 316-318), there were 23 units of the 30b (numbered 346-368), while 4 units were made of the heaviest version, the 30c (numbered 466 to 469). The last class 30 engines were withdrawn from service in 1969. However, engine no. 271 was preserved by the Norwegian Railway Club, and has been used by their department Norsk Museumstog for heritage trains on lines like Raumabanen.
