As of 2019, 137 actresses have been nominated in the category, with a total of 34 different winners. The average age at first nomination is 41 and the average age of winners at first win is 38. With three wins, Dominique Blanc holds the record of most César Award for Best Supporting Actress. Eight actresses have won the César twice: Marie-France Pisier, Nathalie Baye, Suzanne Flon, Annie Girardot, Valérie Lemercier, Julie Depardieu, Anne Alvaro and Karin Viard. Marie-France Pisier and Nathalie Baye have won their two awards in consecutive years. Along with Adèle Haenel, they are the only three performers to have won two competitive acting César in a row. Including her Best Actress César won in 1983, Nathalie Baye is also the only performer to have won an acting César in three consecutive years, in 1981, 1982 and 1983. Noémie Lvovsky and Karin Viard tie for the record of most nominations with 6, Lvovsky also holding the record of most nominations without ever winning the award. Stéphane Audran holds the record of most consecutive nominations with 3. Nine women have won both the César Award for Best Supporting Actress and the César Award for Best Actress:
Nathalie Baye is the only actress with multiple wins in both categories. Three films have received both accolades: One Deadly Summer in 1984, Indochine in 1993 and Queen Margot in 1995. Three women have won the César Award for Best Supporting Actress after previously winning the César Award for Most Promising Actress:
Both Cécile de France and Julie Depardieu have won their two awards with a same role: Isabelle, an Erasmus student, in The Spanish Apartment and its sequel The Russian Dolls for de France, and Jeanne-Marie in Little Lili for Depardieu. Therefore, Depardieu is the only individual to have won two acting César for the same performance. This achievement is no longer possible as the Académie has since modified nomination rules to ensure that no individual could be nominated in more than one acting category for the same film. Three films has received both accolades: An Impudent Girl in 1986, Life Is a Long Quiet River in 1989 and Little Lili in 2004. Thirteen women have received nominations in the three competitive acting categories: Best Actress, Best Supporting Actress and Most Promising Actress. They are Emmanuelle Béart, Charlotte Gainsbourg, Dominique Blanc, Anne Brochet, Karin Viard, Sandrine Kiberlain, Emmanuelle Devos, Cécile de France, Marion Cotillard, Sylvie Testud, Emilie Dequenne, Sara Forestier and Adèle Haenel. So far, no actress has achieved to win the three awards. To date, the most long-lived winner is Suzanne Flon, who died at 87, and the most short-lived is Valérie Benguigui, who died at 47. The oldest alive winner is Hélène Vincent, aged 75, and the earliest alive winner is Nicole Garcia.
International presence
As the César Awards are centered on the French Cinema, the majority of recipients are French and performed in French language. However, the Best Supporting Actress César has been awarded five times to a non-French actress:
in 1995 to Italian actress Virna Lisi for her performance in Queen Margot;
in 2006 to Belgian actress Cécile de France for her performance in The Russian Dolls;
in 2012 to Spanish actress Carmen Maura for her performance in The Women on the 6th Floor;
The Best Supporting Actress César has been awarded only once for a full foreign-language performance with Kristen Stewart's English-language performance. Nevertheless, Virna Lisi's and Carmen Maura's roles included some parts of Italian-language and Spanish-language, respectively. International actresses who have received nominations are:
Belgium: Emilie Dequenne, Cécile de France, Virginie Efira,
Following the AATC's practice, the films below are listed by year of ceremony, which corresponds to the year following the film's year of release. For example, the César for Best Supporting Actress of 2010 was awarded on February 27, 2010 for a performance in a film released between January 1, 2009 and December 31, 2009. Actresses are selected via a two-round vote: first round to choose the nominees, second round to designate the winner. All the members of the Académie, without regard to their branch, are eligible to vote on both rounds. Initially set to four, the number of nominees was expanded to five in 1984. Winners are listed first in bold, followed by the other nominees in alphabetic order.
