Rosa "Ossi" Reichert (25 December 1925 – 16 July 2006) was a German alpine skier.

Her greatest victory was in the 1956 Winter Olympics giant slalom at Cortina d'Ampezzo, Germany's sole gold medal at these games (and Germany's first gold medal in Olympics after the Second World War).

Josefa „Putzi“ Frandl, who won the silver medal in the event, once stated that, "Ossi was disappointed to draw #1 as that was usually not a good position.

"[2] Reichert also participated in the 1952 Winter Olympics in Oslo, where she won a silver medal in the slalom, beating her fellow German Annemarie Buchner for the bronze medal.

She retired the same year to run the hotel of her parents in her home town the Allgäu region.
