Isabelle Autissier (born 18 October 1956) is a French sailor, navigator, writer, and broadcaster. She is celebrated for being the first woman to have completed a solo world navigation in competition (BOC Challenge 1990–91).
While competing in the 1994–95 BOC Challenge Autissier's boat Ecureuil Poitou Charentes II was dismasted and severely damaged approximately 900 nautical miles (1,700 km) south of Adelaide, Australia. Autissier was rescued on 1 January 1995 by a Seahawk helicopter launched from the Royal Australian Navy frigate, HMAS Darwin.
In the 1998–99 Around Alone race Autissier was rescued by fellow competitor Giovanni Soldini when her boat PRB capsized approximately 1,900 miles (3,100 km) west of Cape Horn.
