The Fall and Rise of Reginald Perrin is a British sitcom starring Leonard Rossiter in the title role. Three series were produced from 1976 to 1979, based on a series of novels written by David Nobbs. Nobbs adapted the screenplay for the first series from the first novel. Some of its subplots were considered too dark or risqué for television and were toned down or omitted. A fourth series, The Legacy of Reginald Perrin, also written by Nobbs, followed in 1996.

Leonard Rossiter was an English actor. He had a long career in the theatre but achieved his highest profile for his television comedy roles starring as Rupert Rigsby in the ITV series Rising Damp from 1974 to 1978, and Reginald Perrin in the BBC's The Fall and Rise of Reginald Perrin from 1976 to 1979.
