Lennon Naked is a 2010 television biographical film focusing on the life of John Lennon between 1967 and 1971. It stars Christopher Eccleston as John Lennon and was directed by Edmund Coulthard.

The film was first broadcast on 23 June 2010 on BBC Four, and received its US premiere on PBS on 21 November 2010 as part of Masterpiece Contemporary, airing the day before the American Masters documentary LennoNYC, which begins where Lennon Naked ended. The film premiered in Australia on 5 December 2010.

In 1964, a reluctant John Lennon is persuaded by manager Brian Epstein to meet his father Freddie, who abandoned him seventeen years earlier, with the press in attendance. The reunion does not go well; Lennon and his father get into an argument, and he and Epstein leave angrily.

By 1967, Epstein has died and The Beatles are giving a press conference for their new film, Magical Mystery Tour. Lennon is sceptical about the film, but Paul McCartney convinces him to go through with the idea. Lennon invites his father to his mansion to live with him, allowing Freddie to meet his grandson, Julian.

Sitting with his wife Cynthia, Lennon reads the negative critical reception of Magical Mystery Tour, while comparing Cynthia to Brigitte Bardot, whom he plans to meet after he returns from India. Lennon finds a letter addressed to him, with the word "Breathe" written on it—later revealed to have been written by Yoko Ono. Later, after finding his father in a neighbour's house, Freddie reveals that he has a 19-year-old girlfriend named Pauline, with whom he wants to live. Lennon accuses Freddie of leaving him again and throws him out of the house.

After meeting Maharishi Mahesh Yogi, the Beatles go on a meditation retreat with him, only to return to London shortly afterwards, where they hold a press conference to denounce him as a fraud. That night, before meeting the band's press agent Derek Taylor, Lennon glimpses Yoko from a window. Lennon reveals to Derek that she sends him letters. While on their way to meet Bardot, Lennon tells Taylor he sometimes thinks he is Jesus Christ and, nervous about his meeting the actress, takes a tablet of LSD, as does Derek. The next morning, Lennon, in the midst of a drug trip and, remembering the public's reaction at his "more popular than Jesus" statement two years before, states that he can't walk on water after all. Lennon stays with his childhood friend Pete Shotton in his mansion and asks him to bring Yoko.

After Lennon and Yoko record what will become the album Two Virgins, they spend the night together. Lennon tells Shotton that he wants to live with Yoko. Sometime later, Lennon and Yoko hold a gallery event where Cynthia confronts him about his adulterous affair. Cynthia is willing to forgive Lennon, but he instead chooses Yoko. While Lennon is leaving, Julian is seen playing with a ball all alone, and he throws the ball at his father. Lennon, however, throws it away and doesn't pay attention to his son. Meanwhile, Derek is worried about Apple Records' financial situation and the impending release of the Beatles' eponymous double album. After losing patience with McCartney, Lennon and Yoko leave the meeting and go to their house, and take a picture that will later become the cover of Two Virgins.

Yoko reveals that she's pregnant, but loses the baby in a miscarriage when the police charge her with drug possession. After Lennon proposes to Yoko, he reveals to her at a press conference that his father has had another child – David. Lennon is later seen going through heroin withdrawal, and tells Shotton that Yoko is pregnant again and he needs to clean up the place. Shotton tells Lennon that he must do it himself, and leaves when Lennon refuses. Yoko suffers another miscarriage. In a meeting with the Beatles, Lennon announces to his partners that he is leaving the band. McCartney convinces Lennon not to tell the press. In 1970, after McCartney himself announces he is leaving the Beatles, Lennon throws rocks at McCartney's house.
