Douglas R. Naylor (born 1955) is a British comedy writer, science fiction writer, director and television producer.

Naylor was born in Manchester, England and studied at the University of Liverpool. In the mid-1980s, Naylor wrote two regular comedy sketch shows for BBC Radio 4 entitled Cliché and Son of Cliché, as well as Wrinkles for Radio 4. These sketch shows were scripted by Naylor along with another writer, Rob Grant. This writing partnership was successful with Naylor and Grant going on to co-write and produce numerous BBC television series throughout the 1980s and 1990s. These included programmes such as Comic Relief, Spitting Image, and The 10 Percenters.

The collaborations between Grant and Naylor have often used the pseudonym Grant Naylor. This collaboration is today best remembered for the creation of the British science fiction comedy television series, Red Dwarf (their earlier radio sketch shows formed the basis for the show; Chris Barrie starred in both those and Red Dwarf). This show went on to achieve global cult status.

Robert Grant is a British comedy writer and television producer, who was born in Salford and studied Psychology at Liverpool University for two years.

In the mid-1980s, Grant collaborated with co-writer Doug Naylor on radio programmes such as Cliché and its sequel Son Of Cliché, Wrinkles for Radio 4 and television programmes such as Spitting Image, The 10 Percenters, and various projects for Jasper Carrott.

The 'Grant Naylor' collaboration, as it had become known, was best known for the creation of the cult science-fiction comedy series, Red Dwarf, which evolved from Dave Hollins: Space Cadet, a recurring sketch within Son Of Cliché. Grant was briefly seen (uncredited) in an episode of Red Dwarf entitled "Backwards" (1989), as a man who 'un-smoked' a cigarette.

In the mid-1990s, the 'Grant Naylor' collaboration was ended when Grant left Red Dwarf after the sixth series, citing creative differences ("... it was basically 'musical differences' ...") with Doug Naylor. His main reason however, he said, was that he 'wished to have more on his 'tombstone' than Red Dwarf on its own'.
