This is a list of audio productions based on the long-running British science fiction television series Doctor Who produced by Big Finish Productions.^[1]

These are the season and episode counts for all seasons and series released as of 1 January 2024^[update], ordered by the date that they were initially released.

The dramas feature both former actors who portrayed the Doctor and his companions, and new continuing characters as well as elements from other spin-off media.^[2] The canonicity of the audio dramas, as with other Doctor Who spin-off media, is unclear. To date, productions have featured the Fourth (Tom Baker), Fifth (Peter Davison), Sixth (Colin Baker), Seventh (Sylvester McCoy), Eighth (Paul McGann), War (Sir John Hurt), Ninth (Christopher Eccleston) and Tenth (David Tennant) Doctors portrayed by their original actors. In April 2022, it was confirmed Jo Martin would reprise her role as the Fugitive Doctor in a series of audio adventures.^[3]

Big Finish's current licence from the BBC allows it to produce audio dramas featuring the first twelve incarnations of the Doctor and associated characters introduced into the series between 1963 and 2017. Although Big Finish confirmed in April 2022 that they are producing stories featuring associated characters introduced during the era of the Thirteenth Doctor (Jodie Whittaker), specifically The Fugitive Doctor (Jo Martin) and The Master (Sacha Dhawan), it is not clear whether this includes the Thirteenth Doctor herself.^[4]

Nearly all of the companions from the original series have appeared, voiced by their original actors. They include Susan (Carole Ann Ford), Ian Chesterton (William Russell), Vicki (Maureen O'Brien), Steven Taylor (Peter Purves), Sara Kingdom (Jean Marsh), Polly (Anneke Wills), Jamie McCrimmon (Frazer Hines), Victoria Waterfield (Deborah Watling), Zoe Heriot (Wendy Padbury), Jo Grant (Katy Manning), Brigadier Lethbridge-Stewart (Nicholas Courtney), Sergeant Benton (John Levene), Mike Yates (Richard Franklin), Leela (Louise Jameson), K9 (John Leeson), Romana I (Mary Tamm), Romana II (Lalla Ward), Adric (Matthew Waterhouse), Nyssa (Sarah Sutton), Tegan Jovanka (Janet Fielding), Vislor Turlough (Mark Strickson), Peri Brown (Nicola Bryant), Melanie Bush (Bonnie Langford) and Ace (Sophie Aldred). Adventures featuring revival series companions Rose Tyler (Billie Piper) and Donna Noble (Catherine Tate) have also been released.

Several actors who played the Doctor and companions of previous Doctors have appeared in other roles, including Russell, O'Brien, Marsh, Wills, Watling, Padbury, Caroline John, Manning, Elisabeth Sladen, Leeson, Daphne Ashbrook, Tennant and Bernard Cribbins. Sladen also reprised Sarah Jane Smith in a spin-off series simply entitled Sarah Jane Smith. Sladen never appeared as Sarah alongside any incarnation of the Doctor for Big Finish; a series with Tom Baker was planned, but was never recorded due to Sladen's untimely death in April 2011.

Initially Matthew Waterhouse declined to reprise the role of Adric so the character was recast and played by Andrew Sachs as an older version of the character. Waterhouse later returned to the role on an ongoing basis.

Big Finish also started The Companion Chronicles series of plays, featuring a companion or friend of the Doctor and a supporting cast member. Ford, Russell, O'Brien, Purves, Marsh, Wills, Hines, Watling, Padbury, Manning, Jameson, Tamm, Ward, Sutton, Strickson and Aldred have all reprised their roles in this series along with John (Liz).

As well as this, Big Finish started the Doctor Who: The Early Adventures series of full-cast plays, featuring the First Doctor (recast to William Russell and Peter Purves, following William Hartnell's death in 1975) and the Second Doctor (recast to Frazer Hines, following Patrick Troughton's death in 1987), and companions Barbara Wright (recast to Maureen O'Brien and Jemma Powell, following Jacqueline Hill's death in 1993) and Ben Jackson (recast to Elliot Chapman, following Michael Craze's death in 1998), and Russell, Ford, O'Brien, Purves, Marsh, Wills, Hines, Watling and Padbury reprising their roles from the original series. They also started The Third Doctor Adventures series of full-cast plays, featuring Tim Treloar recast as the Third Doctor (following Jon Pertwee's death in 1996), Manning as Jo, and Franklin as Yates.

Big Finish released The Ninth Doctor Chronicles, a series of plays narrated by Nicholas Briggs and featuring Camille Coduri returning as Jackie Tyler and Bruno Langley returning as the Ninth Doctor's companion Adam Mitchell.^[5]

New companions created for the audio series include Evelyn Smythe (Maggie Stables), Charley Pollard (India Fisher), Erimem (Caroline Morris), Hex Schofield (Philip Olivier), C'rizz (Conrad Westmaas), Lucie Miller (Sheridan Smith), Thomas Brewster (John Pickard), Abby (Ciara Janson), Tamsin Drew (Niky Wardley), Elizabeth Elizabeth Klein (Tracey Childs), Flip Jackson (Lisa Greenwood), Molly O'Sullivan (Ruth Bradley), Liv Chenka (Nicola Walker), Helen Sinclair (Hattie Morahan) and Constance Clarke (Miranda Raison). Lisa Bowerman has appeared as Bernice Summerfield, a companion from the Virgin New Adventures, in several Doctor Who audio dramas as well as in original productions with her as the central character. Robert Jezek and Jemima Rooper have appeared as Frobisher and Izzy Sinclair, companions from the Doctor Who Magazine comic strip, Travis Oliver and Yasmin Bannerman have portrayed companions Roz Forrester and Chris Cwej from the Virgin New Adventures, and Matt Di Angelo has played Fitz Kreiner, a companion from the BBC Eighth Doctor Adventures.

Charley, C'rizz, Lucie, Tamsin and Molly were all referenced by name in the mini-episode "The Night of the Doctor".

In 2005, six of the audio dramas featuring Paul McGann as the Eighth Doctor were broadcast on the digital radio station BBC 7: Storm Warning, Sword of Orion, The Stones of Venice, Invaders from Mars, Shada (originally created for webcast on the BBC's online service), and The Chimes of Midnight. These plays were rebroadcast on BBC7 beginning in July 2006. The Chimes of Midnight was repeated again as part of "The New Eighth Doctor Adventures" Series 1 & 2 in 2009.

In January 2007, a new series of Eighth Doctor audio adventures was broadcast on BBC7. These starred McGann alongside Sheridan Smith as the aforementioned new companion Lucie Miller. There were eight 50-minute episodes in total; the first and last stories were two-parters, and the rest were single episodes. These adventures have since been released on CD. In 2008, BBC7 broadcast the second series of The New Eighth Doctor Adventures (which Big Finish had already released on CD) bar the final two-part story. All fourteen episodes were then repeated in 2009, and the final two-part story later that year. Big Finish has gone on to produce two further series of these Adventures, and four selected stories from the third series were aired in 2010, with BBC Radio 4 Extra (as Radio 7 became) skipping ahead to the fourth series in early 2013.

In May/June 2011, BBC Radio 4 Extra broadcast the Fifth Doctor stories Cobwebs, The Whispering Forest, and Cradle of the Snake. In May/June 2012, these were followed by the Seventh Doctor stories A Thousand Tiny Wings, Survival of the Fittest, Klein's Story and The Architects of History. For the fiftieth anniversary of the show, BBC Radio 4 Extra repeated several stories and broadcast two new stories; Protect and Survive starring Sylvester McCoy and 1963: Fanfare for the Common Men starring Peter Davison. In May 2015, BBC Radio 4 Extra broadcast the first series of Fourth Doctor Adventures starring Tom Baker and Louise Jameson. In 2016, the station broadcast a run of Sixth Doctor adventures: The Crimes of Thomas Brewster (28 May – 4 June),^[6] Industrial Evolution (11–18 June)^[7] and The Curse of Davros (25 June – 2 July).^[8]
