Florelle (born Odette Élisa Joséphine Marguerite Rousseau, 9 August 1898 – 28 September 1974) was a French soprano singer and actress.

Her father, an employee of the town hall, left his job to go into business and the family came to live in Paris; her mother worked at the café La Cigale.

Odette began her stage career at the age of 13, singing at the Théâtre de l'Ambigu-Comique and the Moulin Rouge.

Florelle nevertheless remained attached to the music hall; in 1925, she was chosen as an understudy for Mistinguett and as such was the leader of the Moulin-Rouge review "This is Paris" in a tour of South America.

During the 1930s, she devoted herself a lot to the cinema, where her activity was intense from 1930 to 1936; after L'Opéra de quat'sous, she toured again with Pabst (L'Atlantide), but also with Robert Siodmak (Tumultes), Raymond Bernard (Les Misérables), Fritz Lang (Liliom) and Jean Renoir (The Crime of Monsieur Lange).
