	List of episodes (2005–present)

"The Parting of the Ways" is the thirteenth episode and the season finale of the revived first series of the British science fiction television programme Doctor Who. The episode was first broadcast on BBC One on 18 June 2005. It was the second episode of the two-part story. The first part, "Bad Wolf", was broadcast on 11 June.

In the episode, the Dalek race invades the human satellite Satellite Five in the year 200,100, intending to make more Daleks by harvesting dead humans. The alien time traveller the Ninth Doctor (Christopher Eccleston) plans to use the satellite's transmitter to try to destroy every Dalek, while at the same time sending his travelling companion Rose Tyler (Billie Piper) home to keep her safe.

The episode featured Eccleston making his final appearance as the Ninth Doctor and marks the first appearance of David Tennant as the Tenth Doctor.

The mystery of the reocurring phrase "Bad Wolf", as part of the Series wide mystery box story arc, is resolved in this Episode. The words are revealed to have been scattered in time by Rose herself after she absorbed the Time Vortex, in order to lead herself to that exact moment.
