This is a list of characters from Blake's 7, a media franchise created by Terry Nation.

Kerr Avon is a fictional character from the British science fiction television series Blake's 7, played by Paul Darrow (who is currently recreating the role for the Big Finish Liberator Chronicles and Classic Audio Adventures; in the new B7 audio series, Avon is played by Colin Salmon). Initially one of a character ensemble, he increasingly became a lead character.

A child of the colonies, Avon possesses genius-level intelligence, and is an aloof and sardonic computer expert found guilty of an attempt to embezzle five hundred million credits from the Terran Federation banking system. First seen in the second episode, Space Fall, as a prisoner aboard the London, a cargo vessel transporting a group of convicted criminals to the penal colony on the planet Cygnus Alpha, he assists Blake in his attempted mutiny on the journey, using his skills to take over the ship's computer. He subsequently boards the Liberator along with Blake and Jenna, and becomes a member of the original "seven." The ship's security system caused Avon to see a projection of his brother, nearly killing him until Blake shot the security field.

Avon acts self-serving but in reality, when it comes to actions, he is more selfless than any of the others, constantly saving the lives of almost everyone he comes across and including the entire crew several times over, with nothing to gain for himself.

Avon was far more paranoid during Blake's leadership. He was much less paranoid after Blake left. Avon was a cautious man. He tended to think first before he leapt. As a result, he didn't tend to take as many uncalculated risks.
