Paul Darrow (born Paul Birkby) is a British character actor best known for his portrayal of Kerr Avon in 70s BBC science fiction television series Blake's 7. He also guest starred twice on Doctor Who, most notably playing Tekker (later Maylin) in the serial Timelash.

Darrow was born in Surrey, England, and attended Haberdashers' Aske's Boys' School before studying at the Royal Academy of Dramatic Art. The popularity of his role as Avon has tended to overshadow his extensive work in theatre and television.

He appeared in all but the first episode of Blakes 7. In the final episode of the series, in which all of the main characters are seen to be to be shot, Avon shot dead the character Klyn - played by Paul Darrow's wife, Janet Lees Price.

Darrow's other notable TV appearances include: Emergency Ward 10, The Saint, Z Cars, Dixon of Dock Green, Within These Walls, as the Sheriff of Nottingham in the 1975 BBC series The Legend of Robin Hood, as Thomas Doughty in the BBC series Drake's Venture, Maelstrom, Making News, Pie in the Sky, Hollyoaks and Little Britain. He also spoke the voiceover for Biblical quotations in Richard Dawkin's The Root of All Evil?.

Proud of his work on Blake's 7, Darrow has acted as the show's most prolific spokesperson, both in the UK and during the late 80s, in the U.S., when the show was frequently broadcast on US public television.

In the mid to late 1990s, he has also purchased the rights to Blake's 7 and attempted to produce a big-budget followup miniseries, Blake's 7: A Rebellion Reborn.

According to Darrow, it would have begun 25 years after the ending of the original series and may have included an aged Avon passing the torch to a new generation. Reportedly, due to creative differences, Darrow left the project.
