Øresundslinjen (Swedish: Öresundslinjen) is a ferry company serving the route between Helsingborg, Sweden and Helsingør, Denmark.

The Helsingør–Helsingborg ferry route crosses the narrowest part of the Øresund, taking about 20 minutes to traverse the 4-kilometre (2-nautical-mile) strait.

The company owns five vessels, including the sister ships Tycho Brahe, Aurora af Helsingborg, and Hamlet, each of which has capacity for 240 cars and 1,250 passengers.

In 2018 HH-Ferries rebranded as ForSea Ferries as Aurora and Tycho Brahe were reintroduced into service as battery-electric vessels.

[citation needed] In 2018 the ferries Tycho Brahe and Aurora af Helsingborg were converted to battery power.
