The César Award for Best Actress in a Supporting Role (French: César de la meilleure actrice dans un second rôle) is one of the César Awards, presented annually by the Académie des Arts et Techniques du Cinéma to recognize the outstanding performance in a supporting role of an actress who has worked within the French film industry during the year preceding the ceremony. Nominees and winner are selected via a run-off voting by all the members of the Académie.
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.
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 (1982, 1983, 1984).
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 (Best Actor/Actress or Best Supporting Actor/Actress or Most Promising Actor/Actress) for the same film.
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 (Le Cavaleur, 1980).
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:
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:
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.
