LB (car ferries) or locally simply LB was a car and lorry ferry line that between 1955 and 1981 operated on the HH Ferry route between Helsingør (Elsinore), Zealand, Denmark and Helsingborg, Scania, Sweden. They were the first operator on this route to challenge the informal monopoly which DSB had enjoyed ever since 1888. Since 1630, competition at the route had only occurred between 1836 and 1840. The route had further been operated by the Danish National railways with train ferries since 1892, and since 1931 with a 50-50 support deal also with the National Swedish railway. Until LB challenged the informal monopoly.
