Jedediah "Jed" Dingle is Zak Dingle's estranged father.
In March 2002, it is revealed that Jed - who Zak thought was dead - was alive and had, in fact, walked out on his family when Zak was 8 years old.
Married to Peg, he has at least six sons. Zak manages to track down Jed, who is bedridden in hospital and has to be cared for by a nurse in December 2002. Jed reveals there is a hidden Dingle fortune in Chile and dies shortly afterwards, resulting in Zak heading to Chile for a year in an attempt to find the treasure.
