The Primetime Emmy Award for Outstanding Supporting Actress in a Limited or Anthology Series or Movie is an award presented annually by the Academy of Television Arts & Sciences (ATAS). It is given in honor of an actress who has delivered an outstanding performance in a supporting role on a television limited series or television movie for the primetime network season. The award was first presented at the 27th Primetime Emmy Awards on May 19, 1975, to Juliet Mills, for her role as Samantha Cody in QB VII. The award ceremony garnered criticism during the 58th Primetime Emmy Awards, when Ellen Burstyn received a nomination for her work in Mrs. Harris (2005), despite having only 14 seconds of screen time and 38 words of dialogue. This resulted in a rule change, requiring nominees submitting for the category to have more than 5% screen-time on their respective projects. Since its inception, the award has been given to 38 actresses. Regina King, Jane Alexander, Judy Davis, Colleen Dewhurst, and Mare Winningham have each won two awards. Kathy Bates is the most nominated actress in the category, with seven nominations.
