Zach, portrayed by Kyle Gallner, is a character in the television series The Walking Dead.
Zach is a member of a surviving group of college students who join the prison community. He then begins a relationship with Beth Greene. Zach accompanies Daryl Dixon, Michonne, Glenn Rhee, Tyreese Williams, Sasha Williams, and Bob Stookey on a supply run, where he is ultimately killed by a pair of walkers.
Beth reacts calmly to the news of Zach's death, much to Daryl's surprise. Later, Daryl uses Zach's high-powered car to take himself, Bob, Michonne, and Tyreese on a run to a veterinary college to get medicine that might save the flu-stricken prison group members.
