The Forsyte Saga is a British drama television serial that chronicles the lives of three generations of an upper-middle-class family from the 1870s to 1920s. It was based on the books of John Galsworthy's trilogy The Forsyte Saga, which were adapted by Granada Television for the ITV network in 2002 and 2003. Additional funding was provided by American PBS station WGBH, as the 1967 BBC version had been a success on PBS in the early 1970s.

The Forsyte Saga, first published under that title in 1922, is a series of three novels and two interludes published between 1906 and 1921 by the English author John Galsworthy, who won the 1932 Nobel Prize in Literature. They chronicle the vicissitudes of the leading members of a large upper-middle-class English family that is similar to Galsworthy's. Only a few generations removed from their farmer ancestors, its members are keenly aware of their status as "new money". The main character, the solicitor and connoisseur Soames Forsyte, sees himself as a "man of property" by virtue of his ability to accumulate material possessions, but that does not succeed in bringing him pleasure.
