María Isabel López Rodríguez (born 4 January 1995), known professionally as María Isabel, is a Spanish singer and actress. She is best known for winning the Junior Eurovision Song Contest 2004 with the song "Antes Muerta que Sencilla".
María Isabel was born in Ayamonte, Province of Huelva, Spain. She demonstrated an interest in dancing and singing from a very young age. Her love for singing and dancing took her to the 2004 Spanish Eurojunior competition, which was televised nationally in her native Spain. The purpose of this competition was to select Spain's representative for the relatively new Junior Eurovision Song Contest competition, which began in 2003.
María Isabel won Spain's Eurojunior contest with her single "Antes muerta que sencilla" ("I'd rather be dead than plain"). Subsequently, she won the second Junior Eurovision Song Contest performing the same song, and setting a record for both largest score (171 points) and largest winning margin (31). This record can be explained in part due to the 2004 contest having the highest number of participants of any Junior Eurovision Song Contest, with eighteen participants. Her winning margin record was broken by the 2012 winner, Anastasiya Petryk, who won with a 35-point margin. Her largest score record was broken by 2015 Winner, Destiny Chukunyere.
