Jack McBrayer (born May 27, 1973) is an American actor and comedian. He gained national exposure for his portrayal of characters in "Late Night with Conan O'Brien" and as Kenneth Parcell in 30 Rock, for which he was nominated for Primetime Emmy Award for Outstanding Supporting Actor in a Comedy Series at the 61st Primetime Emmy Awards. He currently is a recurring character in The Middle.

His very distinct voice and "nice guy" persona are also recognisable in voice acting, as he voiced Fix-it Felix Jr., a deuteragonist in Disney's Wreck-it Ralph, and the titular character in Craig Mckraken's Wander Over Yonder, amongst others.

He is going to make his first appearance in the first episode of Season 10 as Randall, Penny's brother.
