The Primetime Emmy Award for Outstanding Supporting Actress in a Drama Series is an award presented by the Academy of Television Arts & Sciences (ATAS). In early Primetime Emmy Award ceremonies, the supporting categories were not always genre-, or even gender-, specific. Beginning with the 22nd Primetime Emmy Awards, supporting actresses in drama have competed alone. However, these dramatic performances often included actresses from miniseries, telefilms, and guest performers competing against main cast competitors. Such instances are marked below:
