Professor River Song is a mysterious archaeologist who shared a close relationship with the Doctor. Although his first meeting with her ended in her death, she told him that, due to the complicated nature of time travel, he had many adventures with her yet to come.

Early Life
River Song was an archaeologist already highly familiar with the Doctor when they first meet (from his perspective) in the 51st century. She was, in fact, a future companion of his who travelled with him off and on. According to her, he trusted her implicitly. Prior to her encounter with the Weeping Angels, she was imprisoned for murder. Whether or not she was guilty is unknown. (DW: The Time of Angels / Flesh and Stone)

Crash of the Byzantium
Doctor River Song was a guest on the Byzantium ship in the 51st century, she was working for a military organisation at the time when that happened. She infiltrated the lower levels to the Home Box, into which she carved the message "Hello Sweetie" in the Old High Gallifreyan language to attract the Doctor. About 12,000 years later the Doctor found the Home Box in a museum. The Doctor used the cube to hone in on her location where she was being pursued by guards. She then jettisoned herself from an air lock, where the waiting Doctor and Amy Pond picked her up in the TARDIS. River then showed exceptional TARDIS flying skills landing it next to the Byzantium, which had crazed into the Maze of the Dead. Along with the Bishop and his Clerics, River accompanied the Doctor and Amy into the maze. (DW: The Time of Angels)

Death
River's expedition to the Library was financed by Felman Lux and was chartered to find out what disaster had happened there, 100 years previously, that had caused 4022 people to "die" or disappear. When her team ran into trouble during an expedition to a deserted library, it was only natural that River should try to summon the Doctor by sending him a message via psychic paper. The version of the Doctor who turned up had not yet met her. Though bewildered, he agreed to help River and her team. River and the Doctor appeared to be very familiar, even considering the strong bonds the Doctor forms with his companions. She kept a worn and battered diary which the cover looked very much like the TARDIS doors, keeping a journal of her travels with the Doctor. There was a suggestion that in the future the Doctor's personal future she would carry a similar journal, as she commenteted about needing to "compare" diaries. She carried a upgraded version of the sonic screwdriver which "her" version of the Doctor had given her. As the situation in the Library deteriorated, River realised she must prove to the Doctor that she was (or will become) someone he trusts completely and with profuse apologies, she whispers his true name into his ear. The Doctor was stunned by this information, and River succeeded in winning his trust.

River physically died when she chose to sacrifice herself in order to stop the Doctor from sacrificing himself in order to save Donna and the other 4022 people trapped in the Library. She pleaded with him to not try and change history, not to change one moment of what is to come for them.

After saving all the trapped people, the Doctor realized his future self must have given her his sonic screwdriver for a reason. Inside he found a data chip, which contains River's Data Ghost. The Doctor saved her by uploading her into the virtual world contained in The Library's data core. CAL, the library's data core controlled by a human girl wired into its mainframe, also managed to save the data ghosts of all of River's dead archaeological team, so she would have company in the virtual world. (DW: Silence in the Library/Forest of the Dead)

When Davros said to the Doctor that "Everywhere you go there are always deaths" River appeared in a flashback, as the Doctor had flashbacks over those who have died during his travels. (DW: Journey's End)

Other Information

 * River Song seemed to take shorter trips with the Doctor, living a more or less normal life between trips, rather than having one extended trip with the Doctor and never seeing him again after parting ways.
 * The Doctor indicates that there is only one event wherein he would or could tell her his true name.
 * Song appears to have knowledge of Time Lord anatomy, including knowledge of regeneration. She also indicates that destruction of both of the Doctor's hearts is a circumstance after which regeneration is not possible.
 * It is also shown that she has the ability to write messages in High Gallifreyan. Using this, she was able to call the Doctor when she needed help, writing 'Hello Sweetie' in Gallifreyan on the Home Box of the Byzantium. (DW: The Time of Angels)
 * River Song is a skilled TARDIS pilot (albeit with very different methods from the Doctor's). She has mentioned that she "learned from the best" but implied that her teacher was not the Doctor. (DW: The Time of Angels)
 * Amy Pond believed River Song to be the Doctor's wife from the future. As yet, this has not been proven or disproven, though in response to Amy's questions, River implied that it was more complicated than a simple marriage relationship. (DW: The Time of Angels)
 * After his experience with River in the Library, the Doctor seemed extremely apprehensive of River, behaving in a somewhat antagonistic manner toward her. (DW: The Time of Angels)
 * It is unknown precisely where in time and space River Song originally came from. As the Doctor has left previous companions in different parts of the universe from where he originally found them, it is possible that River was not originally from the 51st century at all.
