Quillette (/kwɪˈlɛt/) is an online magazine founded by Australian journalist Claire Lehmann. The magazine primarily focuses on science, technology, news, culture, and politics. It also has a podcast, hosted by Jon Kay. Quillette was created in 2015 to focus on scientific topics, but has come to focus on coverage of political and cultural issues concerning freedom of speech and identity politics. It has been described as libertarian-leaning. A 2021 study found Quillette's website to be the 14th most influential internet domain in Australia.
