Fossora is the tenth studio album by Icelandic singer-musician Björk. It was released on 30 September 2022 through One Little Independent Records. The album was recorded mainly during the COVID-19 pandemic and centers around the theme of isolation, loss, and grief, mainly of the death of her mother, Hildur Runa Hauksdóttir, in 2018. Commercially, the album debuted at number 11 on the UK Albums Chart and at number 100 on the US Billboard 200. It received a nomination for Best Alternative Music Album at the 65th Annual Grammy Awards, becoming Björk's ninth consecutive nomination in the category.

Fossora was partially inspired by the 2018 death of Björk's mother, Hildur Rúna Hauksdóttir; the songs "Sorrowful Soil" and "Ancestress" are about her, as well as how Björk dealt with her grief. In the album's liner notes, the former is subtitled "a eulogy for Hildur Rúna", and the latter is subtitled "an epitaph for Hildur Rúna". The album was conceptualized during the COVID-19 lockdowns after Björk travelled to Iceland to record. Keeping with the album's themes, its title is the ungrammatical feminine version of the Latin word for "digger". The album features contributions from American singer Serpentwithfeet, Björk's two children Sindri and Ísadóra, Indonesian dance duo Gabber Modus Operandi, and bass clarinet sextet Murmuri. The album was also set to feature contributions from the Venezuelan producer Arca like Björk's previous two albums Vulnicura (2015) and Utopia (2017), but due to the pandemic, Björk was unable to visit her in Barcelona or to welcome her at home.
