The Prix de la Nonette is a Group 2 flat horse race in France open to three-year-old thoroughbred fillies.
It is run at Deauville over a distance of 2,000 metres (about 1¼ miles), and it is scheduled to take place each year in August.
It was named after the Nonette, a tributary of the Oise in northern France.
The Prix de la Nonette was transferred to Deauville and cut to 2,000 metres in 1980.
The first horse to win both contests was Lezghinka in 1960, and the most recent was Pearly Shells in 2002.
