Viv Groskop (born 8 July 1973) is a British journalist, writer and comedian. She has written for publications including The Guardian, Evening Standard, The Observer, Daily Mail, Mail on Sunday and Red magazine. She writes on arts, books, popular culture and current affairs, often with a feminist slant. She is a stand-up comedian, MC and improviser who was a finalist in Funny Women 2012 and semi-finalist in So You Think You're Funny 2012. She is an agony aunt for The Pool and host of the Mint Velvet clothing podcast "We are Women".

Her first book, I Laughed, I Cried, is an account of Groskop performing one hundred comedy gigs in one hundred nights. It is described as "an experiment in doing what you want, even if it is terrifying, without giving up the day job". It was published by Orion on 27 June 2013. The Anna Karenina Fix, Life Lessons From Russian Literature, was published by Penguin on 5 October 2017.

Groskop was the Artistic Director of the Bath Literature Festival, the first season under her charge being held in February 2014, and the last in 2016 when "the much-loved chief was waved off with a raucous party".
