The War Between the Land and the Sea is a British science fiction drama television miniseries. The series was created by Russell T Davies for BBC One and Disney+ as part of the Doctor Who franchise, known as the Whoniverse.

Starring Russell Tovey and Gugu Mbatha-Raw, the series features UNIT in their attempt to prevent a global war caused by the return of the Sea Devils, now known as "Homo Aqua". Jemma Redgrave, Colin McFarlane, Alexander Devrient and Ruth Madeley reprise their respective roles from Doctor Who and its franchised series. The series was first reported on in July 2024, and filmed from August to December 2024 across Wales, Cardiff and Spain. Of the five episodes, the premiere and finale were written by Davies, with the other three by Pete McTighe.

The War Between the Land and the Sea premiered on BBC One on 7 December 2025 with its first two episodes, and is scheduled to be released on Disney+ in 2026. The series has received generally positive reviews from critics for its performances (particularly Redgrave's) and its similarities to Torchwood.
