This is a list of winners and nominees of the Primetime Emmy Award for Outstanding Guest Actor in a Comedy Series.

Prior to 1988 the category was not gender specific, thus was called Outstanding Guest Performer in a Comedy Series.

These awards, like the other "Guest" awards, are not presented at the Primetime Emmy Award ceremony, but rather at the Creative Arts Emmy Award ceremony.

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.
