Belarus in the Eurovision Song Contest 2009

Belarus was represented at the Eurovision Song Contest 2009 with the song "Eyes That Never Lie", composed by Petr Elfimov, with lyrics by Valery Prokhozhy, and performed by Elfimov himself. The Belarusian participating broadcaster, Belarusian Television and Radio Company (BTRC), selected its entry for the contest through the national final Eurofest 2009. The national final was a televised production which consisted of a semi-final and a final held on 15 December 2008 and 19 January 2009, respectively. Fifteen competing acts participated in the semi-final where the top five entries as determined by a jury panel qualified to the final. In the final, public televoting selected "Eyes That Never Lie" performed by Petr Elfimov as the winner with 11,475 votes.

Belarus was drawn to compete in the first semi-final of the Eurovision Song Contest which took place on 12 May 2009. Performing during the show in position 4, "Eyes That Never Lie" was not announced among the 10 qualifying entries of the first semi-final and therefore did not qualify to compete in the final. It was later revealed that Belarus placed thirteenth out of the 18 participating countries in the semi-final with 25 points.
