"Aliens of London" is the fourth episode of the first series of the British science fiction television show Doctor Who after its revival in 2005. First broadcast on 16 April 2005 on BBC One, it was written by Russell T Davies and directed by Keith Boak. It is the first in a two part story, concluding with "World War Three". The episode is set in London one year after the 2005 episode "Rose". In the episode, the alien crime family the Slitheen fake a spaceship crash landing in the River Thames, putting the Earth on high alert. The Slitheen use the crashed spaceship to lure experts of extraterrestrial life including the "ultimate expert", the alien time traveller the Ninth Doctor (Christopher Eccleston), into a trap inside 10 Downing Street. This episode introduced the character of Harriet Jones, played by Penelope Wilton, who would reprise her role in the episodes "The Christmas Invasion" and "The Stolen Earth". It also featured an appearance by actress Naoko Mori, who went on to feature in the spin off Torchwood as a result of her performance. The Slitheen aliens are part computer generated imagery (CGI) and part prosthetic/costume. "Aliens of London" was watched by seven million viewers on initial broadcast and received generally mixed reviews. The Series wide arc of "Bad Wolf"s appearance in this episode comes in the form of Graffiti, Scribbled onto the side of the TARDIS by an Unnamed Child.

Intending to return Rose to Earth twelve hours after her original departure, the Ninth Doctor miscalculates, arriving twelve months after they left. Rose's mother Jackie is furious with her, believing that Rose had been abducted and murdered. Rose's boyfriend Mickey is also upset, as he was suspected of murdering Rose. As Rose expresses her frustration to the Doctor over not being able to tell the truth of where she had gone, they witness a spacecraft crash through Big Ben and fall into the River Thames. Central London is shut down while the population becomes excited at the possibility of first contact with an alien species. The Doctor suspects trickery and uses the TARDIS to land inside the hospital where the alien pilot has been taken. The Doctor discovers that the alien craft was launched from Earth and that the pilot is really a common pig that has been modified by alien technology. The government is unable to locate the Prime Minister due to the confusion of the crash, and Joseph Green MP is named acting Prime Minister. Green is revealed to be a member of the Slitheen, a family of aliens that uses a device to compress their bodies into large human "suits" resulting in frequent releases of flatulence. Two other high members of the government, Margaret Blaine and Oliver Charles, are also revealed to be Slitheen. The Slitheen secretly celebrate luring the humans into their plan but are unaware of their conversation being witnessed by MP Harriet Jones. When the Doctor returns to Rose, Jackie discovers the truth about the Doctor and the TARDIS and calls it in. They are surrounded by soldiers and escorted to 10 Downing Street. The Doctor is asked to join a panel of alien experts including members of UNIT, and Rose is escorted into the building by Harriet. Harriet tells Rose about the aliens, and together they discover the Prime Minister's corpse. Before they can reveal their discovery, they are caught by Blaine, who begins to unzip her human suit to attack them. At Jackie's flat, a police officer also unzips his human suit and attacks Jackie for being associated with the Doctor. As the Doctor attempts to convince the experts of the forgery of the events, the Doctor realises that the experts have been lured to Downing Street together as part of a trap. Green sends an electrical shock through the assembled group.

The production of the episode was overseen by executive producers Russell T Davies, Julie Gardner and Mal Young, When writing the episode Russell T Davies was inspired by 1958's British science fiction serial Quatermass and the Pit. He was also inspired by Paul Cornell's novel Human Nature for the idea of an antagonistic family. The production team had intended to suggest that the murdered Prime Minister in this episode was the current real life incumbent, Tony Blair. On the DVD commentary for "World War Three", producer Phil Collinson explained that they had hired an actor to play the dead body on the understanding that the man was a Tony Blair impersonator. When the resemblance proved disappointing, they decided to avoid showing the body clearly. The suggestion that the body is Blair's remains when Harriet Jones says that she is "hardly one of the babes", a reference to the large number of female Labour Party MPs who entered the House of Commons in Labour's 1997 general election victory, who were dubbed "Blair's Babes" by the British media. That Tony Blair was elected in Doctor Who continuity was confirmed in "Rise of the Cybermen". The role of Harriet Jones was written specially for Penelope Wilton by Davies. Wilton was drawn to the role because of the quality of the writing; she had previously worked with Davies on Bob & Rose. This episode is the last to have the acronym UNIT stand for United Nations Intelligence Taskforce. It was later changed to Unified Intelligence Taskforce in the Tenth Doctor story “The Sontaran Stratagem” after complaints from the real United Nations. The first round of filming took place on 18 July 2004 at the Cardiff Royal Infirmary which was used as the set for Albion Hospital. The exterior of 10 Downing Street was a replica created a week later in Central London, Extra filming took place at Unit Q2 in Newport, from 20 August to 6 September.

In an interview, Russell T Davies noted that he had to check with the editorial policy before screening the episode because it clashed with the 2005 United Kingdom general election. Overnight figures showed that "Aliens of London" was watched by seven million viewers in the UK, an audience share of 34%. The episode received an Audience Appreciation Index score of 82. When final ratings were calculated, figures rose to 7.63 million. The BBC3 repeat the next Sunday had 598,800 viewers which made it number one in that time slot. In Canada the episode scored 849,000 viewers which made it number 2 for the timeslot across Canada and number 4 in all of primetime for Tuesday nights. This episode, together with "World War Three" and "Dalek", were the first released on the UMD format for the PlayStation Portable. The three episodes were then released on a DVD, then later with the rest of series 1 on a box set. "Aliens of London" received generally mixed reviews. Arnold T Blumburg of Now Playing gave the episode a grade of C, finding the Slitheen, their associated humour, and the pig insulting. However, he was positive towards how the story showed what happened to Rose's home life in her absence. In 2013, Patrick Mulkern of Radio Times described the two parter as "flashy but silly" and "disappointing", though the storyline of Rose's family worked because of the "vivid" characters. He also criticised the execution of the Slitheen and found Eccleston's performance lacking. He particularly praised Wilton's performance, describing her character as the "persistent, inquisitive, heart in the right place Harriet Jones". The A. V. Club reviewer Alasdair Wilkins gave the episode a grade of B−. He found the problem to be more in the execution than conception; there was a possibility of satire in the fart jokes, but the direction and performances let it down. Because it veered close to being silly and not taking the Slitheen seriously, he argued that the televised version did not display its more nuanced parts, like each Slitheen having individuality, the exploration of the human race knowing about extraterrestrials, and Rose's home life. Burk and Smith in Who is the Doctor were more positive. Burk noted that the story was "loved and hated by fans in equal measure" but it was a "delight" for him, though unexpected. While he found the Slitheen to work on many levels of humour, he stated that the domestic storyline was the best part, elevated by good performances. He also felt the pig worked. Smith called it the closest the new series and Davies "ever gets to pastiching the Classic Series' most beloved writer, Robert Holmes." He also praised the domestic situation, though he found the political satire "one note", the direction disappointing, and Eccleston "out of his depth" with lighter moments. There were minor audience complaints with Rose's remark to the Doctor, "You're so gay", generating some controversy. Davies defended himself by saying he was trying to reflect how people talk in real life. The decision to show the next time trailer immediately after the cliffhanger was met with some disdain, with one person writing to the BBC how they were "immediately spoilt by the preview of the second half of the story".
