Jaconda - the planet on which the Sixth Doctor serial The Twin Dilemma is set. It was once a lush, green world with lush meadows and wooded countryside. It was also once well known for its friendly natives. However, in present times, it has become an almost dead, barren and arid planet, with little vegetation. It also smells of rotting vegetables. On some parts of the planet, forests of dead trees can be seen for miles.

Jahoo - one of the twenty-seven planets taken by Davros in "The Stolen Earth".

Jan Francis IX - the planet visited by the Doctor, Romana, Tavius and Janet sometime in TNAODW history.

Junk - one of the planets featured in the New Series Adventures novel Shining Darkness.

Jupiter - the sixth planet from Earth's sun. The fifth planet was destroyed by the Time Lords, and its remains create the asteroid field that lays between Mars and Jupiter. A gas giant, Jupiter has immense gravity. An orbiting space station is the setting for the novel Fear Itself. The planet has many moons including, in the future, Voga.

Justicia - a system of prison planets featured in the New Series Adventures novel The Monsters Inside by Stephen Cole. The Justicia system has lots of planets, six of which are named after letters in the Greek alphabet: Justice Alpha, Justice Beta, Justice Gamma, Justice Delta and Justice Epsilon. There is also another planet called Justice Prime. Rose Tyler mentions her visit to Justicia in the episode "Boom Town", the first explicit reference to a plot point from the novels in the television programme.
