List of Doctor Who audio plays by Big Finish

This is a list of audio productions based on the long-running British science fiction television series Doctor Who produced by Big Finish Productions. The first fifteen monthly releases were made available in both cassette and CD format, with subsequent releases being CD only. Most releases have also been made available as downloads.

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. 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) and Tenth (David Tennant) Doctors portrayed by their original actors.

Big Finish is not licensed by the BBC to produce audio dramas featuring the Twelfth Doctor, as portrayed by Peter Capaldi, or any characters which originate from his era.

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), 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 companion Donna Noble (Catherine Tate) have also been released.
