The Neuekrug-Hahausen–Goslar railway is a double-tracked, non-electrified main line in Lower Saxony in central Germany.

The line, which runs along the northern edge of the Harz mountains, begins in Goslar and forms a junction with the Brunswick–Kreiensen railway to Seesen and Kreiensen at Neuekrug-Hahausen.

It is often described in the local area as the North Harz Line (Nordharzstrecke) but the term may cause confusion.

Here a branch line of the Brunswick Railway Company to Neuekrug-Hahausen was opened on 15 September 1877, which saved east-west goods trains from Halberstadt to Kreiensen having to use the bypass via Salzgitter-Ringelheim.

The old goods line via Grauhof was a victim of the division of Germany and lost its traffic in 1954.
