Orac is a fictional character from the British science fiction television series Blake's 7. The voice of Orac was provided by Peter Tuddenham.

Orac is a highly advanced supercomputer developed by the scientist Ensor, brought aboard the Liberator by Blake and the others at the end of the first series. Ensor was a particularly irascible character and Orac, as his creation, inherited some of his character traits. It is extremely terse and short-tempered and frequently talks down to the humans or refuses to answer questions it deems too simple ("Stardrive"). Avon often lamented that Orac was too valuable to dump. Orac is activated by "a key", that is used by the crew to shut him up if he prattles on too much.

Orac has the ability to communicate with all other computers that carry tarriel cells -- the basic component of all computer systems, designed by Ensor at a young age. It is therefore able to provide the Liberator crew with priceless knowledge. Through calculation of probability, Orac can also predict the future as seen in the series 1 cliffhanger episode (also called "Orac") in which it predicted the destruction of the Liberator. Orac is also able to use its limitless information to derive effective strategies or deduce critical information.

All these systems and abilities combined make Orac an extremely valuable and sought after prize for the Federation. Initially, its creator was planning to sell it to the Federation and medical aid for his heart condition. Servalan offered 100 million credits for it -- an amount that astonished Travis and Blake, although Servalan and Ensor both believed Orac was worth ten times that much. However, Servalan, knowing that Ensor would die without help, sabotaged the returning shuttle, killing both Ensor's son and the medic. She then attempted to steal Orac, only to be stopped by Blake. Unfortunately, Ensor died before he could be brought aboard the Liberator for surgery.

Orac quickly proved its worth when Liberator was re-taken shortly after this by her builders, 'The System'. Even their advanced technology proved no match for Orac, who within hours had completely (and quite possibly lethally) compromised The System itself, as well as deleting their backdoor access into Liberators computer 'Zen'. It would prove its worth again and again, helping devise strategies for penetrating Federation facilities or producing critical information for the crew. Perhaps its greatest service to humanity was when it hacked into the Federation master command strategic computers in the episode 'Star One', alerting Servalan from outside the Galaxy to the invasion force from Andromeda and mobilizing the Federation.

Orac's systems are multi-dimensional; it projects a carrier beam through the same dimension that allows telepaths to transfer thoughts. It is through the hijacking of this beam that an unnamed psychic being attempted to invade the physical plane. It was defeated through Cally's telepathy boosted by proximity to telepathic plants called Moondiscs. To prevent any future incursion by the being, Avon fitted a bomb to Orac that would detonate if its power fluctuated outside of its normal parameters.

This is not the last time that it endangered the crew. Orac had an unquenchable thirst for knowledge. Its desire to study a black hole was so great that it took control of the Liberator and steered it far too close. It states that gaps in its knowledge are "Intolerable" and castigates the crew for their lack of interest in the more fascinating aspects of the Universe.

Orac is presumably a contraction of Oracle. Another theory is that is short for ORal ACknowledgement, referring to Orac's spoken responses. Yet another theory is that because of Orac's ability to communicate with computers that have tarriel cells (ie most computers in the known universe), ORAC is short for Operate and Read All Computers.^{[citation needed]}

Orac on one occasion had a Federation computer perform routine design work for him. Leading Avon to comment, one of Orac's more human-like qualities is that it doesn't like to work. Orac is able to reduce his dimensions and mass to what can be carried in a hand via The Theory of Matter Reduction, which enabled Avon and Vila to sneak it into a casino and win massive stakes at the computer-controlled tables.

Orac was damaged during the destruction of the underground facilities on Terminal ("Rescue"). Repairing it proved beyond even Avon's abilities but Dorian, who had studied with Ensor, was able to get it operating again. Orac was not present during the final shootout on Gauda Prime and is therefore the only member of the Seven whose survival is a certainty. In Tony Attwod's noncanonical "Afterlife", Ensor is shown to have made a twin of Orac for his own use -- called Caro.
