Belarus in the Eurovision Song Contest 2006

Belarus participated in the Eurovision Song Contest 2006 with the song "Mum" written by Andrey Kostyugov and Sergey Sukhomlin. The song was performed by Polina Smolova. The Belarusian entry for the 2006 contest in Athens, Greece was selected through a national final organised by the Belarusian broadcaster National State Television and Radio Company of the Republic of Belarus (BTRC). The national final consisted of a semi-final which was a televised production and an untelevised final held on 10 February 2006 and 27 February 2006, respectively. Fifteen competing acts participated in the semi-final where the top three entries as determined by a public televote qualified to the final. In the final, an eight-member jury panel selected "Mama" performed by Polina Smolova as the winner. The song was later retitled for the Eurovision Song Contest as "Mum".

Belarus was competed in the semi-final of the Eurovision Song Contest which took place on 18 May 2006. Performing during the show in position 5, "Mum" was not announced among the top 10 entries of the semi-final and therefore did not qualify to compete in the final. It was later revealed that Belarus placed twenty-second out of the 23 participating countries in the semi-final with 10 points.
