The presenter's Jimmy Kimmel Live will move forward to a new time of 11.35pm.
The network's Nightline will be pushed back to 12.35am.
The new slot means that Kimmel can directly battle NBC's Tonight Show with Jay Leno and CBS's Late Show with David Letterman.
Jimmy Kimmel Live's new airtime will commence on Tuesday, January 8, the day after ABC's broadcast of the BCS national championship game.
ABC previously cut five minutes off Nightline in early 2011 in order for Kimmel's show to move to midnight.
Jimmy Kimmel Live has seen its best ratings ever in 2012, and surpassed Jay Leno's show for the first time in May.
The host recently stated that he is not a fan of Jay Leno, and has openly mocked his rival on his show.
