Azerbaijan in the Eurovision Song Contest 2021

Azerbaijan was represented at the Eurovision Song Contest 2021 with the song "Mata Hari" written by Amy van der Wel, Josh Earl, Luuk van Beers and Tony Cornelissen. The song was performed by Efendi, who was internally selected by the Azerbaijani broadcaster İctimai Television (İTV) to represent the nation at the 2021 contest in Rotterdam, Netherlands, after she was due to compete in the 2020 contest with "Cleopatra" before the 2020 event's cancellation. Efendi's selection as the Azerbaijani Eurovision entrant was announced on 20 March 2020, while the song "Mata Hari" was presented to the public on 15 March 2021.

Azerbaijan was drawn to compete in the first semi-final of the Eurovision Song Contest which took place on 18 May 2021. Performing during the show in position 14, "Mata Hari" was announced among the top 10 entries of the first semi-final and therefore qualified to compete in the final on 22 May. It was later revealed that Azerbaijan placed eighth out of the 16 participating countries in the semi-final with 138 points. In the final, Azerbaijan performed in position 21 and placed twentieth out of the 26 participating countries, scoring 65 points.
