Newhaven Harbour Railway Station is one of two active stations serving Newhaven in East Sussex, England, the other being Newhaven Town. A third, Newhaven Marine, is legally open, but has no service because its roof is unsafe. Although the line opened in 1847 the station was opened by London, Brighton and South Coast Railway in 1886. Trains are operated by Southern on the Seaford Branch of the East Coastway Line. Beyond the station en route to Bishopstone, the line reduces to single track to Seaford.
