It was Fey's first performance as the former Alaska governor since her iconic impressions during the 2008 presidential campaign when Palin was the Republican vice presidential candidate.
Fey appeared as Palin in a sketch introducing a mock Sarah Palin Network, satirising Palin's entry into media.
Palin recently launched the programme Real American Stories on Fox News Channel and will soon begin production on Sarah Palin's Alaska, an eight-part series for the cable television channel TLC.
Appearing as Palin in a leather jacket with an American flag pin, Fey introduced a lineup of shows like Tea Party Wheel of Fortune (the puzzle read "Obamar is a terrist"), Are You Smarter than a Half-Term Governor? and 30 Main Street, a parody of her own 30 Rock.
Fey made four appearances in 2008 as Palin, earning her an Emmy last year for guest actor.
