The Gribskov Line or the Gribskov Railway is a local passenger railway line in North Zealand north of Copenhagen, Denmark.

The line runs north form Hillerød through the Gribskov forest and splits into two branches to the seaside resort towns of Tisvildeleje and Gilleleje. Connecting the wide belt of holiday homes along the northern coast of Zealand with Copenhagen is an important role of the Gribskov Line.

The railway is standard gauge and single track. It opened in various sections between 1880 and 1924. The distance from Hillerød to either Tisvildeleje or Gilleleje is about 25 kilometres (16 mi), with the total track length being 42.0 kilometres (26.1 mi).

The railway opened in various sections between 1880 and 1924. The first 19.7 km (12.2 mi) long section of the railway line from Hillerød to Græsted opened on 20 January 1880. The next 6.2 km (3.9 mi) long section from Græsted onwards to Gilleleje opened on 14 May 1896. On 16 June 1897 the 6.0 km (3.7 mi) long branch line from Kagerup to Helsinge opened.
