"Someday" is a song performed by all-female German group No Angels. Written and composed by Swedish musicians Thomas Jansson and Niklas Hillbom, it was produced by frequent collaborator Thorsten Brötzmann for the band's third studio album Pure (2003). A latin-flavored pop song, the midtempo ballad's instrumentation includes flamenco guitars, castanets and synthesizers. Lyrically, "Someday" speaks of a woman realizing that her relationship has come to an end, though she is hopeful that she and her love interest will be able to resume their romance in another time and place.

Pure is the third studio album by all-female German pop group No Angels. It was released by Cheyenne Records and Polydor on 25 August 2003. Conceived after the departure of original member Jessica Wahls, the project marked No Angels's first studio release as a quartet and their final album before their temporary disbandment in fall 2003. The remaining four members reteamed with frequent collaborators Thorsten Brötzmann and Peter Ries to work on the majority of the album, with additional songwriting and production contribution from Tobias Lundgren, Perky Park, Nigel Rush, Stephan Ullman, and Twin.
