Belarus competed at the Junior Eurovision Song Contest 2009, which took place in Kyiv, Ukraine.

On 31 March 2009, a professional jury, chaired by Vasily Rainchik, selected 17 songs to compete in the semi-final of the contest.

A professional jury, again headed by Vasily Rainchik, selected ten songs from the 19 to proceed to the final of the event.

"Belakrylyya mary" was the only song in Belarusian language in the running, while all other entries have been performed in Russian.

The winner was determined by a 50/50 combination of votes from a jury made up of music professionals and regional televoting.
