The Tower is a British police procedural television series based on Kate London's Metropolitan trilogy book series. Set in London, it stars Gemma Whelan as police officer Sarah Collins, initially from the fictional DSI department. The first series follows the aftermath of the deaths of a veteran Metropolitan Police officer and a young Libyan girl who fell together from the roof of a London tower block. When Constable Lizzie Adama—one of the only witnesses—disappears soon after, Collins' investigation becomes two-pronged: what happened on the roof, and finding Adama.

Although the series is set in southeast London, it was mostly filmed in the northwest of England, particularly Liverpool and Manchester. The first series of The Tower was broadcast over three 50-minute episodes in November 2021. Patrick Harbinson acted as both screenwriter and executive producer. The show received generally favourable reviews, with positive comparisons being made by critics to fellow police corruption drama Line of Duty; Whelan's acting was considered a highlight. Criticisms were also made, particularly of the sound engineering, which was accused of muffling the spoken dialogue on occasion.
