Ony Paule Ratsimbazafy (born 3 January 1976) is a retired Malagasy sprinter who specialized in the 400 metres.
In 1998 she won the bronze medal at the African Championships,[1] and was therefore selected to represent Africa in 4 × 400 metres relay at the 1998 IAAF World Cup.
The team, with Ratsimbazafy, Amy Mbacké Thiam, Tacko Diouf and Falilat Ogunkoya, finished seventh.
Ratsimbazafy then competed in 4 × 100 metres relay at the 1999 World Championships and 2000 Olympic Games, both times without progressing from the heat, although a national record of 43.61 seconds was set at the Olympics.
