Jenny Alexis Ryan (born 2 April, 1982) has been a Chaser in the British version of The Chase since 2015. Ryan wrote questions for the pilot episode of The Chase in 2009. She was recommended for the show by a fellow Chaser, Anne Hegerty, who had competed on the same quiz team together with her. Ryan's nickname on the show is The Vixen, in reference to her red hair.
Ryan has made appearances also on other quiz shows: Fifteen to One, The Weakest Link, Only Connect, University Challenge (reaching the semi-finals with the University of Leeds), Are You an Egghead? (in 2008 and 2009), and Mastermind (with Buffy the Vampire Slayer as her specialist subject).
Together with Lucy Porter, Ryan hosts Fingers on Buzzers, a podcast about all things quiz.
In an episode aired on 5 September 2019, Ryan went through the whole show without getting a question wrong - the first time that this had happened on the UK version of the show (although an episode where Anne completed the feat aired first). Ryan did this again on 10 February 2020, making her so far the only UK Chaser do it more than once.
