Georgia have been charged over a pitch invasion and for poor organisation of their Group D match at home to Germany on Sunday, which they lost 2-0.
Poland were charged after their fans threw objects during the 1-1 draw away to Ireland in another Group D match the same day, UEFA said.
The Irish were charged with improper conduct of the team, which is automatically brought if a side is shown five or more yellow cards. Both hearings will take place on May 21.
