M/F Tycho Brahe is a Danish battery-electric car-ferry owned by Øresundslinjen that operates on the HH Ferry route. It has been in use since 1991. The ship is bidirectional, which means it can change direction without turning around, so no time is lost for this. The ship is also able to accelerate and decelerate quite quickly to and from her maximum speed of 14 knots.

Øresundslinjen is a ferry company serving the route between Helsingborg, Sweden and Helsingør, Denmark. Until 2018 the company was called HH-Ferries Group, and the trading name Scandlines was used. From 2018 to 2023 the name "ForSea Ferries" was used.
