The Inbestigators (stylised as The InBESTigators) is an Australian mystery children's television series. The show stars Abby Bergman, Anna Cooke, Aston Droomer and Jamil Smyth-Secka as Ava Andrikides, Maudie Miller, Ezra Banks and Kyle Klimson, respectively. The characters are fifth-graders who solve crimes in their school and neighbourhood. Created by Robyn Butler and Wayne Hope, the series has the comic tone of Little Lunch (another series on which they had worked) and an air of mystery. The show aired in two series from 21 June to 30 November 2019 on ABC Me. Netflix released the first and second series in mid-2019 and early 2020 respectively.

The Inbestigators garnered critical acclaim, with praise for its humour and cast, though its characters drew mixed opinions. The show received two AACTA Award nominations for Best Children's Television Series. A spin-off web series, The InBESTigators: Crime Crack, was released in July 2019; a cast Q&A was released in late 2019, followed by a study guide during the COVID-19 pandemic.
