Frank Rossitano is a character played by Judah Friedlander on 30 Rock. After Liz Lemon, head writer and the protagonist of the series, Frank is the most prominently featured writer of the show-within-a-show.

The character always appears wearing a trucker hat with a humorous phrase written on it, which is Friedlander's routine trademark in real life, and large thick-lensed glasses. He lives with his mother and his rent money goes directly to her.

Frank seems to be rather childish, lazy and libidinous.
