I'm a Celebrity...Get Me Out of Here! (often shortened to I'm a Celebrity or I'm a Celeb) is a British survival reality television show, that is broadcast on ITV. It was created by London Weekend Television (LWT) and is produced by Lifted Entertainment. The format sees a group of celebrities living together in extreme conditions with few creature comforts. Each member undertakes challenges to secure additional food and treats for the group, and to avoid being voted out by viewers during their stay, with the final episode's votes nominating who wins a series.

The programme's first series debuted on 25 August 2002 and was filmed within Tully, Queensland, Australia. From the second series in 2003 until 2019, it was filmed around Murwillumbah, New South Wales, Australia. The 2020 and 2021 series were filmed at Gwrych Castle in Wales due to the COVID-19 pandemic, before returning to Australia in 2022. Celebrities participating on the programme nominate a charity to receive a donation from ITV, with the money raised from charges on voting via text, phone or interactive services. Each series has been hosted by Ant & Dec, with the sole exception being the eighteenth series in 2018 when Ant McPartlin suspended his TV appearances for a year, so Declan Donnelly was joined instead by Holly Willoughby.

I'm a Celebrity is often a ratings winner for ITV, attracting on average over 9 million viewers each series, with its success spawning an international franchise of the same name. The main show was accompanied by a sister show from 2002 until 2020 and again from 2024 on ITV2, now entitled I'm a Celebrity: Unpacked, which features behind-the-scenes footage and discussions on celebrities voted out of the latest episode, and clips of the next episode. In 2022, the show won The Sir Bruce Forsyth Entertainment Award at the National Television Awards.

The show will remain on air until at least 2025. In 2023, an all-stars series, I'm a Celebrity... South Africa, was aired. The show's theme music is credited to Grant Buckerfield and contains samples of "Africano" by Earth, Wind & Fire and "Get Out of the House!" by Boom Crash Opera.
