The Diary of River Song is an audio play series from Big Finish Productions. Alex Kingston reprises her character River Song from the television series Doctor Who.[1]
The series is one of the first to prominently feature elements from the revived era (2005 on) of the show; the character of River Song was introduced in "Silence in the Library" (2008) as a time traveller with a mysterious connection to the Tenth Doctor, who does not recognize her. The Rulers of the Universe, the fourth episode of Series 1, sees River crossing paths with the Eighth Doctor, a still younger incarnation. River would appear, again, alongside The Eighth Doctor starting with Doom Coalition 2 and concluding in Doom Coalition 4.
The second series of The Diary of River Song features encounters with both the Sixth and Seventh Doctors.[2][3] The third series, announced September 2017, features an encounter with the Fifth Doctor with Frances Barber reprising her role of Madame Kovarian.[4]
Announced in October 2017, Big Finish confirmed that River Song would return for a fourth and fifth series to be released in 2018 and 2019 respectively. The fourth series features an encounter with the Fourth Doctor;[5][6] whilst the fifth series features encounters with multiple versions of The Master.[7][8]
Big Finish subsequently renewed The Diary of River Song in October 2018, for a further two more series (the sixth and seventh) to be released in 2019 and 2020.[9] In August 2020, the series was confirmed as renewed for its eighth series.[10] Big Finish Productions revealed in July 2021 a ninth series would debut in October 2021.[11]
