1999 Belarusian First League was the ninth season of 2nd level football championship in Belarus. The season started in April 1999 and ended in October 1999.
During the off-season Belcard Grodno (placed 8th last year) merged with Premier League club Neman Grodno (with the latter being renamed to Neman-Belcard Grodno). To fill the two vacant spots, Veino were spared from relegation, and Neman Mosty (placed 3rd in Second League Group B last year) were additionally promoted. Neman Mosty were invited since Veras Nesvizh (Second League Group A runners-up) refused promotion and Gomel-2 (Second League Group B runners-up) were ineligible.
