The 1970 Football Championship of Ukrainian SSR was the 40th season of association football competition of the Ukrainian SSR, which was part of the Second Group of Soviet Class A in Zone 1. It was the eighth and last season in the Second Group of Soviet Class A.
In 1970–1971 the Soviet football league structure went through reformation. The Soviet Class A introduced an extra tier expanding from two to three in total. To the previous First and Second groups, there was introduced Higher (or Top) group. With this, many clubs that previously competed at the second tier (Second Group) were relegated to lower third tier (Second Group). Because of that, many clubs also moved two tiers either up the league's ladder.
All four teams technically were never promoted as they stayed at the third tier. Three clubs were moved from the 1969 Ukrainian Class B, one more from the 1969 Russian Class B, Zone 1.
Note: in 1970, Football Championship of Ukrainian SSR included competitions in both Soviet Class A Second Group (upper level) and Soviet Class B (lower level). Next year 1971, Class B was disbanded, while Class A Second Group was changed to the Soviet Second League.
