It is given in honor of an actor who has delivered an outstanding performance in a guest starring role on a television drama series for the primetime network season.
It has undergone several name changes, originally honoring leading and supporting actors in single appearances on drama and comedy series through 1978.
The award was reintroduced at the 38th Primetime Emmy Awards under the name Outstanding Guest Performer in a Drama Series, honoring actors and actresses in guest starring roles on television drama series.
Beginning with the 77th Primetime Emmy Awards, performers are no longer eligible in guest acting categories if they were previously nominated for a lead or supporting award for playing the same character role in the same series.
Charles S. Dutton, John Lithgow, Ron Cephas Jones and Patrick McGoohan have won the most awards in this category with two each.
