The broadcaster announced that it has picked up the exclusive rights to the new episodes of the classic soap.
The ten-part series, which was ordered by American cable channel TNT in July, will feature original cast members Patrick Duffy, Linda Gray and Larry Hagman.
They will be joined by stars such as Josh Henderson, Jesse Metcalfe, Jordana Brewster, Julie Gonzalo and Brenda Strong.
"We are thrilled to be bringing the new-look Dallas to Channel 5," Channel 5's director of programmes Jeff Ford said.
"With its alluring mix of wealth, seduction, scandal and intrigue, there is something for everyone on the Southfork Ranch and it's a hugely exciting addition to our 2012 schedule."
Dallas will premiere on TNT in summer 2012 but an airdate for Channel 5 has not yet been set.
