Ilse de Lange (born 13 May 1977 in Almelo, The Netherlands) is a Dutch country and pop singer, better known as Ilse DeLange (American spelling).

Ilse de Lange started her career at the age of 8 as a lip-synching artist, in which she won several contests. After she switched over to a live repertoire, she drew attention, through regional and national talentshows in Hilversum (the Dutch centre of televised media). Which got her some live-performances on national television. Ilse de Lange and guitarist Joop Liefland formed a duo. Together with him she was introduced into country music.

She has been very popular in the country / singer-songwriter scene of The Netherlands since 1998 when she released her first album "World of Hurt".

Though she has already worked together with the Italian singer Zuccheroimg, she still lacks international success. She has received an "Edison" prize as best national singer in 2004 and 2009.
