Susanne Aartun Sundfør (Norwegian pronunciation: [sʉˈsànːə ˈòːɣtʉːn ˈsʉ̀nføːɣ] (local Haugesund dialect; [sʉˈsɑ̀nːə ˈɔ̀ʈːʉːn ˈsʉ̀nføːr] in Urban East ("standard") Norwegian); born 19 March 1986) is a Norwegian singer-songwriter and record producer. Born and raised in Haugesund, Sundfør started touring in 2005.

Susanne Sundfør (2007), her self-titled debut studio album, reached number three on the Norwegian album chart. It was followed by Take One in 2008, a live album consisting of songs from her debut. Her second studio album, The Brothel, was released in 2010, peaking at number one in Norway and becoming the best-selling album of that year. The album saw a shift from the piano-driven pop of previous releases towards a more ambitious and electronic direction; its title track reached number two on the Norwegian singles charts, the highest of Sundfør's career. In 2011, she released a live instrumental album composed solely of synthesizers, A Night at Salle Pleyel, serving as a commission piece.

Her third studio album, The Silicone Veil (2012), topped the Norwegian album chart and received critical acclaim. Her international breakthrough came in 2015 with her fourth studio album, Ten Love Songs, which saw Sundfør experimenting with an electronic dance pop sound. The album reached number one and garnered universal acclaim. Her fifth studio album Music for People in Trouble (2017) represented a departure from the electronic-driven sound of previous records in favor of a return to her roots as a folk singer-songwriter. The album reached number one in Norway as well, making it her fourth consecutive album to achieve this feat. Her sixth album Blómi was released in 2023.
