Тhe 2020 Liga 3 season was the fourth one under its current name and 33rd since Georgia formed independent football league system in 1990.
Tbilisi City and Spaeri gained promotion from Liga 4, while Guria Lanchkhuti, Kolkheti-1913 and Tskhinvali were relegated from the second division.
The latter, though, having failed to meet the existing financial commitments, were expelled and replaced by Gareji Sagarejo, a third place team from the lower league.
The teams played opening matches of the season in early March, but as COVID was raging, all sport activities were halted.
The two bottom teams were spared from relegation after some changes regarding the Liga 4 format for the next year were endorsed by Football Federation in February 2020.
