The Fifth Doctor Adventures is a Big Finish Productions audio play series based on the television series Doctor Who. It sees the return of Peter Davison reprising his role as the Fifth Doctor.

In 1999, beginning with the story "The Sirens of Time", Big Finish Productions began producing a series of audio adventures featuring the Fifth Doctor, Sixth Doctor and Seventh Doctor. For 22 years these stories continued collectively known as Big Finish's "Main Range". In May 2020, Big Finish announced the main range would conclude in March 2021 and subsequently replaced with regular releases of each Doctor's adventures continuing in their own respective ranges. Several previously released special titles were retroactively reallocated into these new ranges by Big Finish.

This section includes characters who will appear or have appeared in at least one season.

A second boxset is scheduled for release in September 2024. Big Finish's Creative Director Nicholas Briggs described them as "...really imaginative, celebratory adventures that feel like Classic Doctor Who turned right up to eleven, in the very best of ways".

On 23 May 2024, Big Finish announced their slate of boxsets for 2025. Senior Producer John Ainsworth said "...in 2025, Peter Davison stars in a 12-part Fifth Doctor story for the first time ever. It's an epic featuring new worlds, new creatures and a searing light that could burn everything to dust." The two boxsets are scheduled for release in April and May 2025, respectively.
