Suzy Eddie Izzard (; born Edward John Izzard; 7 February 1962) is a British stand-up comedian, actor and activist. Her comedic style takes the form of what appears to the audience as rambling whimsical monologues and self-referential pantomime.

Izzard's stand-up comedy tours have included Live at the Ambassadors (1993), Definite Article (1996), Glorious (1997), Dress to Kill (1998), Circle (2000), Stripped (2009), Force Majeure (2013) and Wunderbar (2022). She starred in the television series The Riches (2007–2008), and has appeared in numerous films, including Ocean's Twelve (2004), Ocean's Thirteen (2007), Valkyrie (2008), Absolutely Anything (2015) and Six Minutes to Midnight (2020).

Izzard has also worked as a voice actor on films such as Five Children and It (2004), The Wild (2006), The Lego Batman Movie (2017) and the Netflix original series Green Eggs and Ham (2019). Among various accolades, she won two Primetime Emmys for Dress to Kill and was nominated for a Tony Award for her Broadway performance in A Day in the Death of Joe Egg.

In 2009, Izzard completed 43 marathons in 51 days for Sport Relief, despite having no history of long-distance running. In 2016, she ran 27 marathons in 27 days in South Africa in honour of Nelson Mandela, raising £1.35 million. In addition to her native English, she regularly performs stand-up in Arabic, French, German, Russian, and Spanish, and is an active supporter of Europeanism and the European Union.

A dedicated Labour Party activist, she twice ran unsuccessfully for the party's National Executive Committee but temporarily joined as runner-up after Christine Shawcroft resigned in March 2018. In 2022, Izzard attempted to become the party's prospective parliamentary candidate for Sheffield Central, but was not selected in the members' ballot.
