Anthime Joseph "Tim" Gionet (born 1987 or 1988), more commonly known as Baked Alaska, is an American far-right influencer who gained notoriety through his advocacy on behalf of alt-right and white supremacist ideology. He has also used the alias Tim Treadstone.

Prior to his 2016 transformation into an alt-right activist, Gionet was initially a rapper and Internet prankster. He later worked as a commentator for BuzzFeed, where he supported libertarian and progressive political positions and marched in support of Black Lives Matter. In 2016, Gionet turned to the politics of Donald Trump and the alt-right in what he described as a rejection of "political correctness". By 2017, Gionet's political views had radicalized; that year, he began to use his social media platform and Internet activism to promote racist and antisemitic ideologies, which included sharing neo-Nazi content on social media. He also played a role in the 2017 white supremacist Unite the Right rally in Charlottesville, Virginia.

At the beginning of 2019, Gionet claimed to have changed his views and released videos in which he denounced the alt-right and meme culture as sources of terrorism and violence. As part of an attempt to rebrand himself, he gave a series of interviews condemning the alt-right and expressed plans to establish a non-profit organization in order to teach anti-racism to white supremacists. In November 2019, Gionet reverted to his earlier politics, professing far-right ideology and collaborating with the white nationalist Groyper movement. He then began to earn notoriety for his livestreams, in which he would antagonize or harass bystanders, resulting in an assault charge in December 2020.

Originally known as an extremely online personality, Baked Alaska was gradually banned from most mainstream social media platforms. In January 2021, Gionet livestreamed the U.S. Capitol building breach by a pro-Trump mob, which was found to be a violation of his release. It was later reported that Gionet's footage was used by the Federal Bureau of Investigation (FBI) to identify other trespassers. Gionet was later arrested by federal agents that month in connection with his activities at the Capitol. He was released pending trial and continued livestreaming while facing federal charges. On January 10, 2023, Gionet was sentenced to 60 days in jail. Gionet was pardoned by Donald Trump on January 20, 2025.

Gionet was born in Anchorage, Alaska, to a family of eight. His father is a pharmacist and his mother is a nurse. Both his parents are devout Christians who operate a non-profit organization aimed at promoting Christianity and providing medical supplies to orphanages in eastern Russia. During his formative years, Gionet was actively involved in his parents' charity and went to Russia with them numerous times. Five of his siblings were adopted from Russia. As an adolescent, Gionet spent a year and a half in the Russian city of Petropavlovsk-Kamchatsky. He later said that part of his "chaotic nature" may have stemmed from this experience.

In 2006, Gionet left Alaska for Los Angeles and attended Azusa Pacific University, where he graduated with a Bachelor of Science in marketing.

While working at Warner Records, Gionet was a social media and marketing intern for Warped Tour. Kevin Lyman gave him the nickname "Alaska" in reference to where he grew up. In order to make it more "unique", Gionet changed the nickname to "Baked Alaska", a reference to him being a marijuana user and a play on the dessert of the same name.

In 2011, Gionet worked for Capitol Records for a short time, before pursuing his own career in rap music with a "wild, redneck, kick-ass" persona. He kept his nickname Baked Alaska as a stage name. His rap songs used a satirical tone and traded on his Alaskan roots, with titles like "I Live on Glaciers" or "I Climb Mountains". In 2013, the Anchorage Daily News published a profile of Baked Alaska, describing him as a "comedy/music video artist".
