The European football Championship in 2020 will be staged in cities across the continent to spread the financial load of hosting the tournament.
Three of the last four championships have been staged in two countries although it is traditionally held in one.
The idea was first aired by UEFA president Michel Platini at the end of Euro 2012.
UEFA says it had consulted its member associations and received an "extremely positive" response, with Turkey the only one of its 53 members to oppose the idea.
The cost of hosting the tournament, which will increase from 16 to 24 teams in 2016, had been a major factor in the decision.
The bidding process for 2020 host cities will start early next year and will take around 12 months. Decisions on the host countries are expected in early 2014.
