Timothy John Kirkby (born 13 November 1970 in Sidcup, Kent, England) is a British filmmaker working in both the UK and the US. He is best known as the director of the science parody series "Look Around You", the BAFTA-winning BBC 2 show "Stewart Lee's Comedy Vehicle" and the creator of the multi-award-winning series "Fleabag".

Kirkby made his television directing debut with the BAFTA-nominated science parody "Look Around You". Further recognition came with the first season of the BAFTA-nominated series "My Mad Fat Diary", the BAFTA-nominated BBC television drama "The C Word" and, most recently, the critically acclaimed series "Fleabag".

In the US, he created and directed all eight episodes and was also co-executive producer of the award-winning first and second seasons of "Brockmire" for IFC. Other notable directing work on American television includes episodes of the Emmy Award-winning HBO comedy "Veep", "Grace and Frankie", "Brooklyn Nine-Nine", "Man Seeking Woman" and his six-part Netflix series "The Pentaverate", created by Mike Myers, about a secret society that has been working to manage world events since 1347.

He has also filmed documentaries with Motörhead, Iron Maiden and Judas Priest for the multi-award-winning documentary series "Classic Albums", and created and directed all 4 seasons of the critically acclaimed, BAFTA-winning show "Stewart Lee's Comedy Vehicle" — a six-part comedy series of stand-up and sketches. The first season was executive produced by Armando Iannucci, and the scripts were edited by Chris Morris. The first episode received positive reviews from The Independent and The Daily Mirror, although the show received a negative review written by Stewart Lee in Time Out, in which he called himself "fat" and his performance "positively Neanderthal, like a pygmy living in the jungle vainly trying to coax notes out of a clarinet that has fallen from a passing plane". The second season won the BAFTA for Best Comedy Programme in 2012.
