Xylø (stylised in all caps) is the alias of American singer-songwriter Paige Duddy. From 2015 to 2018, Xylø was a musical duo that consisted of Duddy and her brother Chase. Since 2018, Duddy has embarked on a solo career and has continued to release her new music under the Xylø moniker.

As a duo, Xylø was best known for the debut single, "America", which was self-released in February 2015 and saw commercial success online through digital outlets such as NoiseTrade. The single's success resulted in Xylø securing a record deal with Sony Music Entertainment.

Following the departure of Chase in 2018, Paige continued to release new music under the moniker. The releases included four EPs: Pretty Sad, Yes and No, The Ganglands of My Heart and Outsiders Club. All were released under independent label Pretty Records. The title track from Yes & No is her most successful song on Spotify to date, garnering almost 30 million streams as of December 2021.
