"Cry Baby", written and composed by Martin Isherwood, was the United Kingdom's entry at the Eurovision Song Contest 2003, performed by the duo Jemini. It was the first of two songs entered by the United Kingdom to earn no points from any other countries. It was also the first ever English-language song to receive no points.

The Eurovision Song Contest 2003 was the 48th edition of the Eurovision Song Contest. It took place in Riga, Latvia, following the country's victory at the 2002 contest with the song "I Wanna" by Marie N. Organised by the European Broadcasting Union (EBU) and host broadcaster Latvijas Televīzija (LTV), the contest was held at the Skonto Hall on 24 May 2003. The contest was presented by last year's winner Marie N and former contestant Renārs Kaupers.
