Group B of UEFA Euro 2020 qualifying was one of the ten groups to decide which teams would qualify for the UEFA Euro 2020 finals tournament.[1] Group B consisted of five teams: Lithuania, Luxembourg, Portugal (the title holders), Serbia and Ukraine,[2] where they played against each other home-and-away in a round-robin format.[3]
The top two teams, Ukraine and Portugal, qualified directly for the finals. Unlike previous editions, the participants of the play-offs were not decided based on results from the qualifying group stage, but instead based on their performance in the 2018–19 UEFA Nations League.
