Rosenfelspark, Public park in Lörrach, Germany.

Rosenfelspark is a green space covering roughly 2.4 hectares (6 acres) southeast of the town center, with mature trees, animal enclosures, and a music pavilion. Winding paths lead through the park past open meadows and densely planted sections.

Peter Koechlin, manager of a cloth-printing works, acquired an estate east of Lörrach; a plan of 1831 by surveyor J. Hüttinger shows six square beds, a gardener's house with greenhouse, vines on the slope and a pavilion. The English-style landscape park is documented in a notarised deed of 1859. In 1884 a villa replaced the pavilion, and on 20 March 1943 the remaining 1.6 hectares, the villa and the park passed to the city.

The name Rosenfels comes from the Villa Rosenfels built in 1884 on the estate, not from any rock. Since summer the central square with its concert shell closes the Lörrach Stimmen-Festival, and the animal enclosure in the north, free to enter, keeps dwarf goats, Skudden sheep, parakeets, chickens, turtles and ducks.

The park lies at about 300 m above sea level and is almost level; only a few side paths on the eastern edge rise slightly toward the slope. Its path network runs just over a kilometre. There are four entrances on the west side, one to the south and three to the east, and the Stettengasse along the park was made a bicycle street in 2013.

Under the villa, a tunnel was fitted out as an air-raid shelter for mayor Reinhard Boos and the local air-raid protection command, finished at the end of 1944. It runs about 40 metres into the hill and was meant for up to 140 people, with command posts, power for communications equipment, tables, chairs, potatoes and winter vegetables stored inside. No use is documented, and since Lörrach suffered no air raids, it probably never served its purpose.
